No size matches that. Try a number, like 210 , or a name, like Letter
How the standards fit together
There are really only two systems, and one awkward gap between them.
ISO 216 covers most of the world. Every size in the A, B and C series shares the same 1:√2 proportion, which is the whole trick: fold a sheet in half and you get the next size down, with the shape unchanged. A0 starts at exactly one square metre, and A4 is the sheet that fell out of it eight halvings later.
ANSI and the US sizes cover North America. Letter, Legal and Tabloid grew out of manufacturing convention rather than mathematics, so they have no common ratio and no clean halving. Legal is not half of anything.
The gap between them is the reason a document formatted for A4 prints with the wrong margins on Letter, and vice versa. The two sheets are close enough to look identical and far enough apart to cause trouble.
A4 Letter 210 mm 297 mm A4 is 5.9 mm narrower than Letter and 17.6 mm taller, with 103% of its area. Print A4 on Letter at 94%, or Letter on A4 at 97%.
Solid: A4. Dashed: Letter. Hover or tap a sheet for its measurements; hatched strips show where one sheet overhangs the other. Everything else on this page hangs off those two systems, or sidesteps them entirely: photo prints follow camera aspect ratios, books follow binding conventions, and newspapers follow the width of a printing press.

Longer answers to the questions that come up once you know the dimensions.
Standard paper size Letter or A4: which one is printer paper where you live, what it weighs, and how to set it. Change the default paper size Set A4 or Letter as the default in Windows, macOS, Word, Google Docs and your printer, so it stops coming back. Paper size equivalents The nearest ISO size for every US and ARCH sheet, and the exact scale to print one on the other. Paper sizes in pixels Every size at 72, 96, 150, 200, 300 and 600 dpi, and the arithmetic behind it. What a sheet of paper weighs Grams per sheet for every common size and paper weight, plus what a full ream comes to. Sheets, quires and reams How paper is counted, and why old books disagree about the quire. Portrait and landscape The same sheet, turned. Both orientations for every common size. Foolscap explained Three different sheets share the name. Which one someone means, and why. Postcard sizes What posts as a postcard, from A6 to the US 4 × 6, with mailing limits. Poster sizes Every standard poster size, what each is used for, and what to send the printer. Not sure which size you have?
Measure the sheet and use the paper size finder , which names any size from a width and height in any unit. If you already know what you are holding, the two sizes almost everyone meets first are A4 outside North America and Letter inside it.
