How Google Docs Measures Page Size (72 PPI)
Google Docs™ uses points as its internal unit of measurement. One point equals exactly 1/72 of an inch, which means Google Docs operates at 72 PPI (points per inch). When you set a page width of 8.5 inches, Google Docs stores that value as 612 points (8.5 x 72).
This matters because many design and image-editing tools default to 96 PPI — the standard screen resolution on most displays. If you are preparing images or graphics to paste into a Google Docs document, you need to know both the 72 PPI values (what Google Docs uses internally) and the 96 PPI values (what your screen actually renders).
Complete Google Docs Built-In Page Size Reference Table
The table below lists every page size available natively in Google Docs™ Page Setup. All values are calculated from the official inch dimensions.
| Size Name | Inches (W x H) | Centimeters (W x H) | Millimeters (W x H) | Pixels at 72 PPI (W x H) | Pixels at 96 PPI (W x H) |
|---|---|---|---|---|---|
| Letter | 8.5 x 11 | 21.59 x 27.94 | 215.9 x 279.4 | 612 x 792 | 816 x 1056 |
| Tabloid | 11 x 17 | 27.94 x 43.18 | 279.4 x 431.8 | 792 x 1224 | 1056 x 1632 |
| Legal | 8.5 x 14 | 21.59 x 35.56 | 215.9 x 355.6 | 612 x 1008 | 816 x 1344 |
| Statement | 5.5 x 8.5 | 13.97 x 21.59 | 139.7 x 215.9 | 396 x 612 | 528 x 816 |
| Executive | 7.25 x 10.5 | 18.42 x 26.67 | 184.2 x 266.7 | 522 x 756 | 696 x 1008 |
| Folio | 8.5 x 13 | 21.59 x 33.02 | 215.9 x 330.2 | 612 x 936 | 816 x 1248 |
| A3 | 11.69 x 16.54 | 29.7 x 42.0 | 297 x 420 | 841.68 x 1190.88 | 1122.24 x 1587.84 |
| A4 | 8.27 x 11.69 | 21.0 x 29.7 | 210 x 297 | 595.44 x 841.68 | 793.92 x 1122.24 |
| A5 | 5.83 x 8.27 | 14.8 x 21.0 | 148 x 210 | 419.76 x 595.44 | 559.68 x 793.92 |
| B4 | 9.84 x 13.9 | 25.0 x 35.3 | 250 x 353 | 708.48 x 1000.8 | 944.64 x 1334.4 |
| B5 | 6.93 x 9.84 | 17.6 x 25.0 | 176 x 250 | 498.96 x 708.48 | 665.28 x 944.64 |
For ISO paper sizes (A3, A4, A5, B4, B5), pixel values at 72 PPI are not round numbers because these sizes originate from the metric system. The values above are mathematically exact.
Common Custom Page Sizes (Not Built Into Google Docs)
Google Docs™ only offers the 11 sizes listed above through its native Page Setup menu. If you need a different size — for self-publishing, photo books, postcards, or any non-standard format — you will need an add-on like DocSize to set a custom page size.
For a step-by-step walkthrough, see our guide on how to set a custom page size in Google Docs.
| Size Name | Use Case | Inches (W x H) | Centimeters (W x H) | Millimeters (W x H) | Pixels at 72 PPI (W x H) | Pixels at 96 PPI (W x H) |
|---|---|---|---|---|---|---|
| 6 x 9 | KDP / Book publishing | 6 x 9 | 15.24 x 22.86 | 152.4 x 228.6 | 432 x 648 | 576 x 864 |

| 8 x 10 | Photo book | 8 x 10 | 20.32 x 25.4 | 203.2 x 254.0 | 576 x 720 | 768 x 960 |
| 4 x 6 | Postcard | 4 x 6 | 10.16 x 15.24 | 101.6 x 152.4 | 288 x 432 | 384 x 576 |
| 8 x 8 | Square format | 8 x 8 | 20.32 x 20.32 | 203.2 x 203.2 | 576 x 576 | 768 x 768 |
To use any of these sizes in Google Docs, install DocSize from the Google Workspace™ Marketplace and enter your custom width and height directly. DocSize also lets you set custom margins and background colors — all for free.
Unit Conversion Formulas
If you need to convert between units yourself, here are the exact formulas used throughout this reference:
- Inches to Centimeters: multiply by 2.54 (e.g., 8.5 in x 2.54 = 21.59 cm)
- Inches to Millimeters: multiply by 25.4 (e.g., 8.5 in x 25.4 = 215.9 mm)
- Inches to Pixels at 72 PPI: multiply by 72 (e.g., 8.5 in x 72 = 612 px)
- Inches to Pixels at 96 PPI: multiply by 96 (e.g., 8.5 in x 96 = 816 px)
To go the other direction:
- Pixels (72 PPI) to Inches: divide by 72
- Pixels (96 PPI) to Inches: divide by 96
- Centimeters to Inches: divide by 2.54
Simple math, but easy to mix up when you’re bouncing between tools. That’s what this page is for.
Why Pixel Dimensions Matter
Why would you care about pixels in a word processor? A few reasons:
Screen display and zoom levels. Google Docs renders your document on screen using pixels. Understanding the pixel dimensions at 96 PPI (the standard screen resolution) helps you predict how large your document will appear on a monitor and how it will look when exported as a PDF or image.
Sizing images for your document. When you insert an image into Google Docs, it is displayed at screen resolution. If you want an image to fill the full width of a Letter-size page (minus margins), you need to know that the printable area is approximately 624 pixels wide at 96 PPI (8.5 inches minus 1 inch of default margins = 6.5 inches x 96 = 624 px).
Design tool interoperability. Tools like Canva, Figma, and Photoshop work in pixels. If you are creating a header image, cover page, or graphic element for a Google Docs document, matching the correct pixel dimensions ensures your content fits without unexpected scaling or cropping.
Export and sharing. When you download a Google Docs document as a PDF or print it, the dimensions map back to physical units. Knowing the relationship between pixels, points, and inches helps you maintain consistent output quality.
Default Margins for Each Built-In Page Size
Google Docs™ applies 1-inch (2.54 cm) margins on all four sides by default for most page sizes. Here is a summary of the default margin behavior and the resulting printable area for the most commonly used sizes:
| Size Name | Default Margins (all sides) | Printable Area in Inches (W x H) | Printable Area at 72 PPI (W x H) |
|---|---|---|---|
| Letter | 1 in (2.54 cm) | 6.5 x 9 | 468 x 648 |
| A4 | 1 in (2.54 cm) | 6.27 x 9.69 | 451 x 698 |
| Legal | 1 in (2.54 cm) | 6.5 x 12 | 468 x 864 |
| A5 | 1 in (2.54 cm) | 3.83 x 6.27 | 276 x 451 |
| Tabloid | 1 in (2.54 cm) | 9 x 15 | 648 x 1080 |
| Executive | 1 in (2.54 cm) | 5.25 x 8.5 | 378 x 612 |
For smaller page sizes like Statement (5.5 x 8.5) or custom sizes such as 4 x 6, 1-inch margins may consume too much of the page. You can adjust margins through File > Page setup in Google Docs, or use DocSize to set precise custom margins alongside your custom page size.

Frequently Asked Questions
What is the pixel size of a Google Docs page?
The default Google Docs™ page is US Letter size, which measures 612 x 792 pixels at 72 PPI (the internal resolution Google Docs uses) or 816 x 1056 pixels at 96 PPI (standard screen resolution). If you are using A4, the dimensions are 595 x 842 pixels at 72 PPI or 794 x 1122 pixels at 96 PPI.
Does Google Docs use 72 or 96 PPI?
Google Docs uses 72 PPI internally. This is inherited from the PostScript point system, where 1 point = 1/72 inch. However, most computer screens render at 96 PPI, so the on-screen pixel dimensions differ from the internal point values. Both columns are included in the reference tables above so you can use whichever value applies to your workflow.
Can I set a custom page size in Google Docs?
Google Docs™ natively supports 11 preset page sizes (Letter, Tabloid, Legal, Statement, Executive, Folio, A3, A4, A5, B4, and B5). To set any other size — such as 6 x 9 for KDP book publishing or 4 x 6 for postcards — you need the DocSize add-on. It is free and works with any Google Workspace™ account. For detailed instructions, read our custom page size guide.
How do I convert Google Docs page dimensions to pixels?
Multiply the width or height in inches by the PPI value you need. For Google Docs internal resolution, multiply by 72. For standard screen resolution, multiply by 96. For example, an 8.5-inch-wide Letter page is 612 pixels at 72 PPI (8.5 x 72) or 816 pixels at 96 PPI (8.5 x 96). All conversions for every built-in size are listed in the reference table at the top of this page.
Summary
That covers every built-in Google Docs™ page size and the most common custom sizes. Remember: 72 PPI for internal/print dimensions, 96 PPI for screen display. When in doubt, check the tables above.
