Points to Inches Converter
This free points to inches converter turns typographic points into inches (and inches back into points) instantly. Because 72 points always equal 1 inch, the ratio is fixed and DPI-independent — the same value everywhere, on screen or in print. The conversion is bidirectional, so enter a figure in either field to see the other update. Everything runs entirely in your browser: nothing is uploaded and there is no signup, so your measurements stay private.
How to use the points to inches converter
- Enter your type size or measurement in the Points field.
- Read the inches value, which updates instantly as you type.
- To go the other way, type into the Inches field and read the points — the tool is fully bidirectional.
- There is no DPI setting to worry about: 72 points is always exactly 1 inch.
- Copy the result into your design software, print layout, or style sheet.
Every calculation happens locally in your browser, so nothing you enter is uploaded, stored, or shared.
The points to inches formula
A point (the PostScript or DTP point used in modern software) is defined as exactly one seventy-second of an inch. That makes the conversion a simple division:
inches = points ÷ 72
To reverse it, multiply instead: points = inches × 72. For example, 36 pt ÷ 72 = 0.5 in, and 0.25 in × 72 = 18 pt.
Unlike converting points to pixels, this needs no DPI value. Both points and inches are absolute physical units, so 1 pt = 1/72 in is a fixed ratio that never changes with screen resolution. (Points to pixels is different: 1 pt = DPI ÷ 72 px, which is 1.333 px at 96 DPI but 1 px at 72 DPI — that conversion depends on resolution, this one does not.)
Points, picas, and typography
The point is the traditional unit of font size. When you set text at “12 point,” you are describing the type size in points, not the height of any single letter — the visible cap height and x-height sit well below the full point size, since the point measure includes space for ascenders, descenders, and a little breathing room.
Points come from the world of print and desktop publishing (DTP), where type has been measured this way for centuries. Software such as InDesign, Illustrator, Word, and Photoshop all size type in points by default. The next unit up is the pica: 1 pica = 12 points, and 6 picas = 1 inch. Picas are handy for column widths and layout grids, while points handle finer measures like type size, leading, and rule weights. The converter above supports picas too — switch either unit dropdown to Picas (pc) to convert points, inches, or millimetres to and from picas.
Point systems: why 72 points (and not 72.27)
If you have seen a converter claim that an inch holds roughly 72.27 points, it is not wrong — it is just using an older point system. Several definitions of the “point” have existed over the centuries, and they disagree slightly. The tool above uses the modern PostScript/DTP point (exactly 72 per inch), which is the standard in every mainstream design application today. The table below shows how the main systems compare.
| Point system | Points per inch | 1 point equals | Where you meet it |
|---|---|---|---|
| PostScript / DTP (modern) | 72 | 0.3528 mm | InDesign, Illustrator, Photoshop, Word, CSS pt |
| Traditional / printer’s (American) | 72.27 | 0.3515 mm | Old metal type, some legacy print specs |
| TeX point | 72.27 | 0.3515 mm | TeX / LaTeX typesetting |
| Didot point (European) | ≈67.54 | 0.3759 mm | Continental European typography; 12 Didot points = 1 cicero |
The differences are tiny — the traditional and PostScript points sit about 0.4% apart — but they matter for precise print reproduction of historical work. For anything you create in modern software, treat 72 pt = 1 in as exact, which is what this converter does. The pica scales with whichever point system you use: 1 pica is always 12 points, so a PostScript pica is exactly 1/6 inch, while a traditional pica is a hair larger.

Common font sizes in inches and millimetres
Because type is specified in points, it helps to know how everyday sizes translate into physical measurements for print work. These figures are exact regardless of the device or resolution:
- Body text (10–12 pt): roughly 0.14–0.17 in, or 3.5–4.2 mm.
- Captions and footnotes (8–9 pt): about 0.11–0.13 in, or 2.8–3.2 mm.
- Subheadings (14–18 pt): 0.19–0.25 in, or 4.9–6.4 mm.
- Headlines (24–36 pt): 0.33–0.5 in, or 8.5–12.7 mm.
Points to pixels: when DPI does matter
Points to inches is fixed, but if you need points in pixels, resolution enters the picture. Use pixels = points × (DPI ÷ 72). At the legacy screen value of 72 DPI, 1 pt = 1 px. On the modern web default of 96 DPI, 1 pt = 1.333 px, so 12 pt becomes 16 px. Reach for a dedicated pixel converter whenever you are heading to a screen, and stick with this tool whenever inches or millimetres are the goal.
Frequently asked questions
How many points are in an inch?
There are exactly 72 points in an inch. This is the modern PostScript/DTP point used by all mainstream design and publishing software, so 72 pt always equals 1 in.
How do I convert points to inches?
Divide the number of points by 72: inches = points ÷ 72. For example, 18 pt ÷ 72 = 0.25 in. Or just type the value into the converter above and read the result instantly.
How big is 12pt in inches?
12 pt is 0.1667 in (that is 12 ÷ 72, or one sixth of an inch), which works out to about 4.23 mm. Note this is the type size, not the printed height of the letters, which is smaller.
Does converting points to inches depend on DPI?
No. Points and inches are both absolute units, so 1 pt = 1/72 in is a fixed ratio that never changes with resolution. Only converting points to pixels depends on DPI, because pixels are resolution-dependent.
How many points are in a pica?
One pica contains 12 points, and 6 picas make up 1 inch. Picas are often used for column widths and layout measures, while points handle type size and leading.
How do I convert inches back to points?
Multiply the inches by 72: points = inches × 72. For instance, 0.5 in × 72 = 36 pt. The converter does this automatically when you type into the inches field.
Is 72 pt really exactly one inch?
Yes, for the PostScript/DTP point that all current software uses. Older systems occasionally used slightly different definitions (such as the traditional point of about 1/72.27 in), but you can treat 72 pt = 1 in as exact today.
Is this points to inches converter free and private?
Yes. It is completely free, requires no signup, and runs entirely in your browser. Nothing you enter is uploaded to a server, so your measurements stay on your device.
