The serif axis that matters, and the two rows that break the table
There are twenty six serif families in the 150 most-used Google Fonts. Five of them carry an optical size axis, which is the axis that matters most in this category and the one almost nobody checks for. Nineteen are variable fonts, seven are static, and five ship no italic at all.
Two rows also quietly break the comparison. Noto Serif SC and Noto Serif JP are CJK families carrying tens of thousands of glyphs, at roughly 24MB and 13MB against a category median under 300KB. Reading the size column without noticing that leads to the wrong conclusion about every other family in it.

Weights counts roman styles, with matched italics after the plus. Families with one axis show its range; families with several show the first three axis names and a count of the rest, with full ranges in the profiles below. Rank is the position within the 150 families our census covers. Every name links to its own page with full licence terms.
What an optical size axis actually does
A serif drawn for body text and the same serif drawn for a headline are not the same drawing. At 12pt a face needs open counters, sturdy serifs and generous spacing to survive being small. At 72pt those same features look clumsy, and what the eye wants instead is finer hairlines, sharper serifs and tighter spacing. For centuries this was solved by cutting separate sizes of the same face, and the knowledge was largely set aside when one scalable outline became the norm.
An optical size axis restores it. The designer draws both ends and everything between, and the renderer picks the right drawing for the size being set. Five families here expose one: Merriweather, Roboto Serif, Literata, Playfair and Fraunces.
The practical consequence is specific. A serif without an optical size axis is a compromise tuned for one size range, and using it far outside that range is where headlines end up looking slightly muddy or body text ends up looking spindly. Most people diagnose that as the wrong typeface. Often it is the right typeface at the wrong size, with no mechanism to adapt.
The two rows that break the size column
File sizes in this category run from 36KB to roughly 24,500KB. That is a spread of nearly seven hundred to one, and it is entirely the work of two rows.
Noto Serif SC covers Simplified Chinese and Noto Serif JP covers Japanese. A Latin family needs a few hundred glyphs. A CJK family needs tens of thousands, and the file size follows directly. Neither is bloated; they are doing a completely different job from everything around them.
This matters because a reader scanning the size column will calibrate against the largest number they see. Against 24MB, Merriweather at 4.5MB looks reasonable and Arvo at 36KB looks impossibly light. Against the twenty four Latin families alone, the median is under 300KB and Merriweather is one of the heaviest things in the category. Both readings come from the same column. The lesson is not really about fonts: a table containing two rows drawn from a different population will mislead about every other row in it unless the table says so out loud.
One family here is carrying dead languages
Cardo covers Gothic, Hebrew, Old Italic and Runic, and it is the only family in this category covering any of them. It also covers Greek and extended Greek, which together give it the widest script coverage in the set.
That is not a general-purpose feature and it is not an accident. Cardo was drawn for classicists, medievalists and biblical scholars, who need to set Hebrew alongside Greek alongside a runic inscription in a single paragraph, and who have historically had to assemble that from three or four separate fonts with mismatched proportions.
For anyone not doing that work none of this matters, and Cardo is simply an unremarkable static serif with two weights. For anyone who is, it is close to the only option in the corpus. It is the clearest case in this category of a family whose entire value sits in a field most people never look at.
The most recognisable serifs here are the least distinguishable
This page profiles the families the data can actually separate, and three of the best-known serifs in the set do not qualify. Crimson Pro, Cormorant Garamond and Libre Baskerville each carry zero facts that are true of them and false of most of their siblings. Playfair Display, at rank 27 one of the most-used serifs on the web, carries one.
That is not a criticism of any of them, and it is worth stating plainly because the omission would otherwise read as a judgement. Being a well-drawn, conventionally specified, widely useful book serif is exactly the thing that does not show up in an axis list. These families are popular because the drawing is good, and the drawing is the one property this page has deliberately refused to invent claims about.
It cuts the other way too. Fraunces has more measured facts than almost anything here, including two axes nobody else exposes, and it is the lowest-ranked family in the set at 106. Distinctiveness in metadata and usefulness in practice are different quantities, and this page only measures the first.
Five families ship no italic
Roboto Slab, Cinzel, Prata, Noto Serif SC and Noto Serif JP ship no italic styles at all.
For a serif this is a heavier constraint than it is for a sans, because the italic is doing more work. Serif italics are not slanted romans; they are a genuinely different drawing descended from a different hand, and in running text they carry emphasis, titles, foreign phrases and citations. A serif without one is missing a register that serif-set prose actively uses.
For the two CJK families the absence is expected, since the concept does not transfer. For Roboto Slab, Cinzel and Prata it is a real limitation worth knowing before committing a body-text setting to any of them.
The 19 the data actually distinguishes
The table above holds all 26 families in the category, and every one of them links to its own page. The 19 below are the ones carrying at least two measured facts that are true of them and false of most of their siblings. The remainder are not worse typefaces. They are families the metadata cannot separate, and inventing a distinction for each of them would be the opposite of useful.
- A width axis (87 to 112)
- An optical size axis (18 to 144)
- The highest-ranked family in the set at number 14
The highest-ranked serif in the set at 14, and one of five here with an optical size axis, which it pairs with a width axis. That combination is why it holds up across a range of sizes better than most of its neighbours. At roughly 4.5MB it is the heaviest Latin family in the category by a wide margin, which is what carrying three axes across seven weights and matched italics costs. Drawn for screen reading at text sizes, and the specification backs that up.
- One of only 7 here covering Greek
- One of only 6 here covering extended Greek
- One of only 2 here covering Math
- A width axis (62.5 to 100)
- The widest script coverage in the set at 8 subsets
- The most roman weights in the set at 9
- Credited to Google, who drew 3 of the 26 families here
- A weight axis reaching down to hairline at 100
- The widest weight range here, 100 to 900
Nine weights with nine matched italics, a width axis, a weight axis reaching hairline, and the widest script coverage of any Latin family here at eight subsets including Greek, extended Greek and the maths set. It is the most complete system in the category and it is built to be exactly that: the Noto project exists to cover every script, and this is its serif. If one serif has to serve a multilingual project, the argument for looking here first is strong.
- One of only 7 here covering Greek
- One of only 6 here covering extended Greek
- No italic styles at all
- The most roman weights in the set at 9
- A weight axis reaching down to hairline at 100
- The widest weight range here, 100 to 900
Nine weights on a weight axis reaching hairline, and no italic at all, which is unusual for a family this complete in every other respect. It covers Greek and extended Greek. The missing italic is the fact to weigh: nine weights give plenty of range for hierarchy, and none of that range substitutes for the register an italic carries in running prose.
- One of only 2 here covering Math
- The only family here covering the symbols set
Four weights with four matched italics, covering the maths subset and the only family in the category covering the symbols subset. Those two coverages are the measured distinction, and they matter for anyone setting technical or academic prose where an equation or a technical mark should not fall back to a different face mid-line. Otherwise a conventional and well-liked book serif at 212KB.
- The most roman weights in the set at 9
- A weight axis reaching down to hairline at 100
- The widest weight range here, 100 to 900
Nine weights with nine matched italics on a weight axis reaching hairline, which is the widest weight range in the category alongside Noto Serif and Roboto Slab. A slab serif drawn for screens, and one of the few families here offering a genuinely complete roman and italic pairing across the full range rather than at two or three stops.
- Static instances only, no variable axis
- The smallest download in the set at 36KB
- The narrowest script coverage in the set at 1 subsets
The smallest download in the category at 36KB, roughly a seven-hundredth of Noto Serif SC and an eighth of the Latin median. Two weights with two matched italics, static, and the narrowest script coverage here at a single subset. A slab serif that does one thing at one size, and the file size is honest about that: there is no axis and no extended coverage to carry.
- Static instances only, no variable axis
- The fewest roman weights in the set at 1
One weight with one matched italic, static, and the fewest weights in the category alongside Prata, Instrument Serif and DM Serif Text. A slab serif in the same territory as Arvo but with a single setting rather than two. At 72KB it is among the lightest here, which follows directly from having no axis and two styles.
- The only family here covering Chinese-simplified
- No italic styles at all
- The largest download in the set at 24537KB
- Credited to Google, who drew 3 of the 26 families here
The largest file in the category at roughly 24,500KB, and one of the two rows that distort the size column for everything else. It is the only family here covering Simplified Chinese, which is the entire explanation: a CJK family carries tens of thousands of glyphs where a Latin family carries a few hundred. Eight weights and no italic, since the concept does not transfer. Judge it against the other Noto CJK family, never against the Latin families beside it.
- The only family here covering Japanese
- No italic styles at all
- Credited to Google, who drew 3 of the 26 families here
The only family here covering Japanese, at roughly 13,250KB the second largest file in the category and the other row that breaks the size comparison. Eight weights, no italic. Everything said about Noto Serif SC applies: this is a different kind of object from the Latin families around it, and the only fair comparison is with its sibling.
- A width axis (50 to 150)
- An optical size axis (8 to 144)
- Unregistered axes most families do not expose (GRAD)
- The most roman weights in the set at 9
- A weight axis reaching down to hairline at 100
- The widest weight range here, 100 to 900
The most heavily specified family in the category: a width axis, an optical size axis, a grade axis that most families never expose, nine weights and nine matched italics, and a weight axis reaching hairline. Grade lets weight be adjusted without changing the width the text occupies, which is genuinely useful when text sits in a fixed layout and needs to look heavier on a dark background. Very few families in the whole corpus expose it.
- One of only 7 here covering Greek
- One of only 6 here covering extended Greek
- An optical size axis (7 to 72)
One of five families here with an optical size axis, with eight weights and eight matched italics and coverage of Greek and extended Greek. It was drawn for reading on a screen at length, and the optical size axis is the part of that brief doing the real work: the same family adapts from a chapter heading to a footnote rather than compromising between them.
- No italic styles at all
- Static instances only, no variable axis
- The fewest roman weights in the set at 1
A single weight, no italic, static, at 99KB. It is one of four families here with the fewest weights in the category, and the absence of an italic in a face this high-contrast is a real constraint on using it for anything longer than a heading. A display serif in a category mostly built for text, and the specification says so clearly.
- One of only 7 here covering Greek
- One of only 6 here covering extended Greek
Five weights with five matched italics, covering Greek and extended Greek, at 784KB. A revival of a sixteenth century face, and the Greek coverage is more than a bonus here: Garamond-era typography and Greek scholarship are historically entangled, so a Garamond with a real Greek is doing something its ancestors did.
- Static instances only, no variable axis
- The fewest roman weights in the set at 1
A single weight with one matched italic, static, 69KB, covering two script subsets. One of the four families with the fewest weights in the category. A high-contrast display serif, and like Prata it is specified for one confident setting rather than for a system.
- The only family here covering Gothic
- One of only 7 here covering Greek
- One of only 6 here covering extended Greek
- The only family here covering Hebrew
- The only family here covering Old-italic
- The only family here covering Runic
- Static instances only, no variable axis
- The widest script coverage in the set at 8 subsets
The most unusual family in the category by a distance. It is the only one covering Gothic, Hebrew, Old Italic or Runic, and combined with Greek and extended Greek that gives it the widest script coverage here. Drawn for classicists and medievalists who need those scripts to sit together in one paragraph at matched proportions. Two weights, static, one italic, 329KB. For anyone outside that work it is an ordinary serif; for anyone inside it, close to unique in the corpus.
- Static instances only, no variable axis
- The fewest roman weights in the set at 1
A single weight with one matched italic, static, 73KB, two script subsets. One of four families here with the fewest weights. It has a display sibling in the wider Google Fonts library, which is the practical reason to reach for it: the two are drawn to pair, so a heading and its body text can come from the same hand without either being set at the wrong size for its drawing.
- One of only 7 here covering Greek
- One of only 6 here covering extended Greek
Six weights with six matched italics, covering Greek and extended Greek, at 416KB. It was drawn specifically for literature and long-form reading, and the complete roman and italic range across six weights is what that brief requires. One of the better-equipped text serifs here that is not part of a large system family.
- A width axis (87.5 to 112.5)
- An optical size axis (5 to 1200)
One of five families with an optical size axis, paired with a width axis, and distinct from Playfair Display which also appears in this category. Seven weights with seven matched italics. The optical size axis is the substantive difference between the two: this one adapts across sizes where its more famous sibling is drawn for display and stays there.
- An optical size axis (9 to 144)
- Unregistered axes most families do not expose (SOFT, WONK)
- The most roman weights in the set at 9
- The lowest-ranked family in the set at number 106
- A weight axis reaching down to hairline at 100
- A credited team of 3
- The widest weight range here, 100 to 900
The lowest-ranked family in the set at 106 and the most distinctive in specification, with nine weights, matched italics, an optical size axis, a weight axis reaching hairline, and two axes almost nothing else exposes: softness and wonk. Wonk toggles the more eccentric letterforms in and out, which is a designer handing over a decision most families make for you permanently. Credited to a team, one of the few here. A face for people who want to tune character rather than pick it.
Common questions
How many serif fonts are in the 150 most-used Google Fonts?
Twenty six. Serif is the second-largest of the five categories in that set, behind Sans Serif at 95 and ahead of Display at 13, Handwriting at 8 and Monospace at 7. The highest-ranked serif is Merriweather at 14.
Which serif fonts have an optical size axis?
Five of the twenty six: Merriweather, Roboto Serif, Literata, Playfair and Fraunces. An optical size axis means the face is drawn differently for small and large sizes, restoring something that was standard in metal type and set aside when one scalable outline became the norm. It is the axis that matters most in a serif and the one least often checked.
Why are some of these fonts so much larger than others?
Two rows are CJK families. Noto Serif SC covers Simplified Chinese at roughly 24MB and Noto Serif JP covers Japanese at roughly 13MB, because those scripts need tens of thousands of glyphs where a Latin family needs a few hundred. Excluding those two, the category median is under 300KB and the range runs from 36KB to about 4.5MB.
Which serif font covers Hebrew or ancient scripts?
Cardo, and only Cardo. It covers Gothic, Hebrew, Old Italic and Runic as well as Greek and extended Greek, which gives it the widest script coverage in the category. It was drawn for classical and medieval scholarship, where those scripts have to be set together at matched proportions.
Which serif fonts have no italic?
Five: Roboto Slab, Cinzel, Prata, Noto Serif SC and Noto Serif JP. For the two CJK families the concept does not transfer. For the other three it is a genuine limitation, because a serif italic is a separate drawing rather than a slanted roman and carries emphasis, titles and citations in running prose.
Are these serif fonts free for commercial use?
Every family in the 150 most-used set is under an open licence, almost all of them the SIL Open Font License 1.1, which permits commercial use, monetised video, broadcast, merchandise, client work and logos with no attribution required. The licence forbids selling the font software on its own and requires a modified version to be renamed. Each family page on this site records its exact licence with a source URL and a verification date.
Method and sources. Category, licence, designer credits and popularity rank come from our own typeface census, which reads the Google Fonts metadata API and the licence files in the google/fonts repository, and records a licence only with a source URL and a verification date. Weights, italics, variable axes, script subsets and byte size come from the Google Fonts metadata API read on the build date shown above. Popularity rank is the position within the 150 families the census covers, not the global ordering. Families are profiled individually only where the metadata carries at least two facts true of them and false of most of their siblings; the rest appear in the table, and the page says so rather than implying the profiled families are the better ones. Every family named here links to its own page on this site with its full licence terms. Built 2026-08-29.
