About mm and pt
Millimeters are the metric unit for physical dimensions used in print specifications worldwide, while points are the Anglo-American typesetting unit fixed at 1/72 of an inch (25.4mm). Since these two systems developed independently — one metric, one derived from imperial measurement — converting between them always involves the same recurring decimal factor (2.83465), which is why print and design software need a reliable converter rather than a memorized round number.
mm to points for print production and layout
Setting up bleed and trim in design software
Print shops specify bleed and trim margins in millimeters, but layout software like InDesign and Illustrator work natively in points and picas. Converting a printer's mm spec to points lets a designer set document guides that exactly match the physical print requirements, avoiding mismatches that could cause content to be cut off or leave unwanted white borders.
Meeting minimum text-size regulations
Packaging, signage, and accessibility regulations sometimes mandate a minimum physical letter height in millimeters. Because cap height is only about 70-75% of a font's nominal point size, converting the mm requirement to points and then adjusting for that ratio avoids under-sizing text that technically fails a legal or accessibility minimum despite looking "close enough" on screen.
Working with international print specifications
European, Asian, and most non-US print specifications use millimeters throughout, while typesetting and font sizing worldwide still commonly use points regardless of the region. Designers regularly bridge these two systems when receiving a metric-region print brief but working in points-based layout software, making mm-to-pt conversion a routine part of international print production.
1 mm = 2.835 points. A 10 pt font renders at 3.527 mm cap height (approximately). Standard book margins: 20-25 mm = 56.7-70.9 pt. Understanding the mm-to-pt conversion is essential when bridging design briefs (in mm) and typesetting software (in points).

Frequently asked questions
How do I convert mm to pt?
To convert mm to pt, multiply by 2.83465. Or use the calculator above for instant results.
How many pt are in 1 mm?
1 mm equals 2.83465 pt.
Why does 1mm equal 2.83465 points and not a round number?
The modern DTP point is fixed at exactly 1/72 of an inch, and an inch equals exactly 25.4mm — so 1mm converts to 72 ÷ 25.4 = 2.83465 points. It's a recurring decimal because the point system was built around inches, not millimeters.
How do I convert print-shop bleed and margin specs from mm to points?
Print shops typically specify bleed (usually 3mm) and trim margins in millimeters, while layout software defaults to points. Converting a 3mm bleed to points (about 8.5pt) lets a designer set exact matching document guides.
What font size in points matches a given cap height in mm?
Cap height is typically 70-75% of a font's nominal point size, not the full size. A 10pt font (3.53mm) typically has a cap height around 2.5-2.6mm — important for signage and accessibility minimums.
Why do European and Asian print specs use mm while US design software uses points?
Most countries outside the US use metric measurements for physical dimensions, while points survive in design software as a holdover from Anglo-American typesetting tradition that predates the metric system.
Is the mm to pt converter free?
Yes, the mm to pt converter is completely free with no sign-up required, no downloads, and it works offline once the page has loaded.
