Instantly convert between typographic points and centimeters
This PT to CM converter lets you switch between typographic points and centimeters in real time. No formulas to remember. No manual math.
Points (pt) are a unit of measurement used in typography and print design. One point equals exactly 0.035278 centimeters, or about 1/72 of an inch. Centimeters belong to the metric system and are standard in most print and physical design workflows outside the US.
Use the preset buttons for the most common sizes. Use the swap toggle when you need to go in the other direction. Results are precise to 6 decimal places.
A PT to CM converter is a calculation tool that transforms typographic point values into centimeter measurements using a fixed mathematical ratio.
Input is a point value. Output is the centimeter equivalent. No estimation, no rounding unless you choose it.
The tool is used in print design, CSS styling, and document formatting workflows where type specifications in points need to translate into physical, measurable dimensions.
Why it matters: designers often work across two parallel systems. Type specs live in points. Page dimensions and physical layouts live in centimeters. The converter bridges that gap without manual math.
The conversion is based on the PostScript point standard, which is the universal reference used by Adobe software, CSS, and every major design tool today.
A typographic point is a fixed unit of measurement used to specify font size, leading, and type-related dimensions in print and digital design. The current standard is the PostScript point: 1 pt = 1/72 of an inch, which equals 0.035278 cm exactly.
This standard was established by Adobe and Apple in the 1980s and has since become universal across design software and printing systems (Gamut Packaging, 2025).
These are 2 distinct point standards, and they produce different results:
|
Standard |
Value |
Used In |
|---|---|---|
|
PostScript point |
1/72 inch = 0.035278 cm |
CSS, Adobe, Figma, Word |
|
Didot point |
0.03761 cm |
Traditional European typography |
Key difference: If your converter uses the Didot standard, 72 pt will not equal 2.54 cm. It'll be slightly larger. Most modern tools default to PostScript.
The Didot point still appears in some older European print workflows and legacy typesetting systems. For anyone working in contemporary design, PostScript is the correct reference.
Points appear in 3 main contexts in active design work.
Print production: font size, tracking, kerning, and line height in InDesign, Illustrator, and similar tools are all specified in PT.
CSS: the pt unit is a valid CSS length unit. Some email clients, including Outlook, still render font sizes in points rather than pixels (LinkedIn/Kristen Joseph, 2021).
Document formatting: Microsoft Word and Google Docs use PT for font sizes by default, even in regions where the interface shows centimeters for page margins.
A centimeter is a metric unit equal to 1/100 of a meter, standardized by the International System of Units (SI). In design and print, it is an absolute unit with a fixed physical size, which makes it directly convertible to PT using a constant ratio.
CM is used for physical print dimensions, page margin settings, and paper size specifications like A4 (21 × 29.7 cm) and A3 (29.7 × 42 cm).
Where it shows up in design tools:
Microsoft Word and Google Docs default to CM for page layout in most non-US regions
InDesign and Illustrator allow users to set the document ruler to CM for layout dimensions
Packaging and label specs are almost always delivered in CM or MM
The global commercial printing market reached $501.36 billion in 2024 (Revenue Memo, 2026). Most of that output is specified using metric measurements for physical dimensions, with PT reserved for type.
Practical distinction: CM is what you'd verify with a ruler. PT is what you'd set in a type panel.
The formula is: CM = PT × 0.035278
This ratio is fixed and derived directly from 2 known constants: 1 pt = 1/72 inch, and 1 inch = 2.54 cm.
The math is straightforward:
1 pt = 1/72 inch
1 inch = 2.54 cm
Therefore: 1 pt = 2.54 ÷ 72 = 0.035278 cm
No rounding at the formula level. The result to 6 decimal places is 0.0352778. For print work, 4 decimal places covers all practical use cases.
72 pt = exactly 2.54 cm = exactly 1 inch. That's the anchor value worth knowing by memory.
To go the other direction: PT = CM ÷ 0.035278
Or equivalently: PT = CM × 28.3465
Quick reference:
1 cm = 28.3465 pt
2.54 cm = 72 pt (1 inch)
0.035278 cm = 1 pt
The table below covers the point values used most often in typography and print layout, from body text sizes through display type.

Body text runs 10–12 pt (0.353–0.423 cm). Subheadings sit between 14–18 pt (0.494–0.635 cm). Display type at 48–72 pt reaches 1.693–2.540 cm, large enough to measure by hand.
Note on paper margins: a standard 2.5 cm page margin equals 70.87 pt. A 1 cm margin equals 28.35 pt. These values come up often when a printer requests all specs in one unit.
Manual conversion takes 3 steps.
Step 1: Take your PT value.
Step 2: Multiply by 0.035278.
Step 3: Round to the decimal precision your workflow requires (2 places for most print work, 4 places for tight tolerance jobs).
Example 1: 12 pt body text
12 × 0.035278 = 0.4233 cm
Example 2: 72 pt display heading
72 × 0.035278 = 2.54 cm (exactly 1 inch)
Example 3: 36 pt subheading
36 × 0.035278 = 1.27 cm
The 72 pt example is the best sanity check. If your manual calculation gives you exactly 2.54 cm, you're using the PostScript standard correctly.
Sans-serif fonts are used in 65% of modern print designs (Smashing Magazine). Most of those font sizes are originally specified in PT, then converted when physical print specs are required.
PT-to-CM conversion comes up in 5 real workflows consistently.
Print production handoffs: clients in metric regions request all specs in CM. The designer works in PT for type, then converts before delivery.
Cross-region collaboration: US designers default to PT and inches. European clients work in CM. Took me a few confusing file handoffs before I started converting proactively.
Packaging and label design: physical dimensions are always in CM or MM. Text size specs arrive in PT. Both need to coexist in the same spec sheet.
Document formatting: Word and Google Docs use CM for page setup, PT for font size. Converting between them is necessary when a client asks for unified specs.
CSS print stylesheets: browser-based converters and the cm CSS unit both accept physical measurements. A designer moving values from an InDesign print file into a CSS print stylesheet needs the exact CM equivalents.
Both tools let you set the document ruler unit independently from the type unit.
In InDesign: Edit > Preferences > Units & Increments. Set the ruler to centimeters for layout work while keeping the Character panel in points for type.
In Illustrator, the same logic applies. Page artboard dimensions in CM, text frames measured in CM from the ruler, font size always in PT.
90% of design firms worldwide engage in print-related projects annually (Design Week). Most of those projects require exactly this kind of unit switching.
Word defaults to CM for page margins in most non-US regions, and PT for font size.
A standard A4 document with 2.5 cm margins has those margins set at 70.87 pt if expressed in type units. Word handles this translation internally, but knowing the conversion matters when producing spec sheets or working across teams using different tools.
Google Docs behaves identically. Page setup uses CM. Font panel uses PT. The 2 systems don't conflict, but they require manual reconciliation when unified specs are needed.
Related converters for adjacent workflows: PX to CM for screen-to-print work, PT to PX when moving from print specs to screen, and CM to PX when the direction reverses entirely.
Type size ranges follow a fairly consistent logic across print production. Body text, subheadings, and display type each occupy a defined band in the PT scale.
Body text (9–12 pt = 0.3175–0.4233 cm)
This is the range most readers find comfortable for long-form print. Times New Roman, originally designed in 1931 for newspaper legibility, was set at 11–12 pt. Most professional print projects stay in this band for running text.
Subheading range (14–18 pt = 0.4939–0.6350 cm)
Used for section headers, pull quotes, and labels. 14 pt sits just above body text. 18 pt is clearly distinct without requiring display-weight treatment.
Display and heading range (24–72 pt = 0.8467–2.54 cm)
Anything above 24 pt reads as a heading at normal print distances. 72 pt equals exactly 1 inch, or 2.54 cm, which is the most reliable anchor value in the whole PT system.
Sans-serif fonts account for 65% of modern print designs (Smashing Magazine). Most of that type is originally specified in PT, then converted when physical specs are requested.
A note on minimum legible sizes: 6 pt = 0.2117 cm is generally the floor for fine print in packaging, disclaimers, and legal copy. Below that, most readers can't read it without a magnifier.
Not every conversion from PT lands in CM. The right output unit depends on the output medium and the region you're working in.
|
Output Unit |
Best For |
Avoid When |
|---|---|---|
|
CM |
Metric-region print, page layout, packaging |
US print specs, screen work |
|
MM |
Tight tolerances, label design, fine print |
Large-format layout |
|
Inches |
US print, US letter/tabloid specs |
Metric-region clients |
|
PX |
Screen and web output |
Any physical print job |
MM is more precise for small measurements. A 1 pt difference at body text size is 0.035 cm, but 0.353 mm. For packaging labels where tolerances matter, MM gives you more usable decimal places without reaching scientific notation.
CM is the better choice for larger layout dimensions: page margins, column widths, bleed settings.
Straightforward split. US-standard paper formats (Letter, Legal, Tabloid) work in inches. International formats (A4, A3, B5) work in CM.
72 pt = 1 inch exactly. That clean ratio makes inch conversion especially easy to verify.
These are fundamentally different conversions. CM is a physical unit. PX to CM conversion depends on screen resolution (DPI), which varies by device. PT to CM does not.
Use PX when the output is a screen. Use CM when you're printing.
For adjacent conversions in CSS workflows: PX to PT, PX to EM, and PX to REM cover the screen-side unit relationships. PT to PX handles the reverse when moving print specs into digital contexts.
Not all converters are equal. The standard matters more than the interface.
PostScript: 1 pt = 0.035278 cm. Used by CSS, Adobe software, Figma, Word, and virtually every modern design tool.
Didot: 1 pt = 0.03761 cm. Found in some European legacy systems and older typesetting references.
The difference is small at body text sizes. At 12 pt, it's 0.4233 cm (PostScript) vs. 0.4513 cm (Didot). That's a 0.028 cm gap. Not catastrophic, but it compounds at larger sizes and over multiple specs.
Most online converters use PostScript without saying so. If a tool doesn't specify, test it: enter 72 pt. The result should be exactly 2.54 cm. Any other result means the tool is using a different standard.
3 reference values to verify any converter:
72 pt = 2.54 cm (the primary check)
1 pt = 0.035278 cm (single-unit precision)
28.3465 pt = 1 cm (reverse direction check)
If all 3 pass, the converter is using the PostScript standard correctly.
Precision settings matter too. A tool that rounds to 2 decimal places shows 12 pt as 0.42 cm instead of 0.4233 cm. For most print work, that's fine. For tight-tolerance packaging jobs or multi-column layouts where small errors stack, use a tool that outputs 4+ decimal places.
Adobe InDesign's built-in unit conversion uses the PostScript standard to 4 decimal places by default. When Adobe released InDesign 2024, it retained the same unit conversion engine used since the PostScript standard was formalized in 1985 (Computer History Museum, 2023).
For color-related conversions alongside your type work: RGB to HEX Converter, HEX to RGB Converter, and the Type Scale Generator help round out a complete print spec workflow.
Other unit converters in the same family: MM to PX, Inch to PX, REM to PX, and EM to PX for screen-to-print and screen-to-screen conversions.
Multiply your point value by 0.035278. That's it. The formula is CM = PT × 0.035278, based on the PostScript standard where 1 pt = 1/72 inch and 1 inch = 2.54 cm.
1 typographic point equals 0.035278 cm. This is the PostScript point standard used by CSS, Adobe InDesign, Illustrator, Figma, and Microsoft Word. The Didot point gives a slightly different result at 0.03761 cm.
12 pt equals 0.4233 cm. This is a standard body text size in print design. At this size, the physical measurement is small enough that rounding to 2 decimal places (0.42 cm) works fine for most print production workflows.
72 pt equals exactly 2.54 cm, which is also exactly 1 inch. This is the most useful anchor value in the entire PT system. If a converter gives you any other result for 72 pt, it's using the wrong standard.
PT is an absolute unit. It has a fixed physical size that doesn't change based on screen resolution, parent element, or browser settings. This makes it reliable for print specifications, unlike relative units like em or rem used in responsive web typography.
PT is a physical print unit tied to inches. PX is a screen unit tied to device resolution. They aren't directly interchangeable without knowing the DPI of the output device. For print work, always convert to CM, MM, or inches rather than pixels.
Type specifications use points. Page dimensions and physical layouts use centimeters. When a printer or client requests unified specs in one unit, or when working across US and metric-region teams, PT to CM conversion is part of the standard handoff process.
Adobe InDesign and Illustrator both handle it natively via unit preferences. Microsoft Word and Google Docs manage it internally between page setup (CM) and font panels (PT). Browser-based converters are useful for quick one-off conversions without opening design software.
Divide the centimeter value by 0.035278, or multiply by 28.3465. So 1 cm = 28.3465 pt, and 2.54 cm = 72 pt exactly. Use this when a printer spec is in CM and you need to match it in a type panel set to points.
CSS supports both, but PT is not recommended for screen-based font sizing. Most web designers use px, rem, or em for responsive layouts. PT in CSS is treated as a physical unit and can behave inconsistently across devices. Reserve PT for print stylesheets only.
