PDF Page Size Reference Chart (Free Printable)
Designing a flyer, exporting a report, or printing a document that needs to look right the first time? The most common cause of blurry prints and cropped PDFs is mixing up page sizes and DPI. This free printable PDF page size reference chart puts every common size in one place: A4, Letter, Legal, A3, A5, A6, and B5, with exact dimensions in inches and millimeters plus the pixel sizes you need at 72, 150, and 300 DPI. Whether you are exporting from a design tool, setting up a document template, or just wondering how big A5 really is, this one-page chart saves you a search every single time.
What’s inside this pack
The chart covers the seven sizes people actually encounter. US office workers live in Letter and Legal, most of the rest of the world lives in the A-series from A3 to A6, and B5 shows up in books and planners. For each size you get width and height in inches, millimeters, and pixels at three DPI levels, so you can set up a document in any tool without doing math. A short DPI guide explains when 72 is enough (screen only), when 150 does the job (everyday office printing), and when you need 300 (professional print). Keep it pinned next to your workspace and you will never export a blurry PDF again.
The PDF page size chart (free sample)
Here is a free sample showing the four most-used page sizes with their 300 DPI pixel dimensions, the ones you will need most often. The full downloadable pack includes all seven sizes, pixel values at 72, 150, and 300 DPI, and the quick DPI guide, formatted as one clean page you can save, print, or keep open while you work.
| Page size | Inches (W x H) | Millimeters (W x H) | Pixels at 300 DPI (W x H) |
|---|---|---|---|
| A4 | 8.27 x 11.69 | 210 x 297 | 2480 x 3508 |
| US Letter | 8.5 x 11 | 215.9 x 279.4 | 2550 x 3300 |
| US Legal | 8.5 x 14 | 215.9 x 355.6 | 2550 x 4200 |
| A5 | 5.83 x 8.27 | 148 x 210 | 1748 x 2480 |
How to use this pack
- Find your target size in the chart and note the pixel dimensions at your chosen DPI.
- In your design or export tool, create the document at exactly those pixel dimensions.
- For print work, always pick the 300 DPI column. For screen-only PDFs, 72 DPI keeps the file small.
- Double-check the aspect ratio before exporting, especially when switching between A4 and Letter.
- Save the chart somewhere handy, like your desktop or a pinned browser tab.
- Share it with teammates so everyone exports at the same settings.
Getting page size and DPI right at the start avoids the classic problems: text cut off at the edges, images that look sharp on screen but fuzzy on paper, and PDFs that printers reject. One quick look at the chart replaces all of that guesswork.
Frequently asked questions
What is the difference between A4 and US Letter?
A4 is 210 by 297 mm and US Letter is 215.9 by 279.4 mm, so Letter is slightly wider but shorter. If you print an A4 document on Letter paper without scaling, the bottom gets cut off, which is exactly why having both on one chart matters.
What DPI should I use for a printable PDF?
Use 300 DPI for anything going to a print shop or meant to look professional. 150 DPI is acceptable for internal office documents and home printers. 72 DPI is fine for PDFs that will only ever be viewed on a screen.
Why do my exported PDFs look blurry when printed?
Almost always because the export used screen resolution (72 or 96 DPI) instead of 300 DPI. Re-export using the pixel dimensions from the chart’s 300 DPI column and the blur disappears.
