Paper Size Charts
This list of the common American and European paper sizes includes the ISO standards, which are used globally. All dimensions are specified in inches.
American paper sizes
The US and Canada do not use the international standards but instead rely on the paper sizes below. The ANSI standard was added in 1995 to create a set of sizes that are based on shared dimensions. It lacks however the consistent aspect ratio of the ISO A-series.
Size | Inches | Millimeters |
---|---|---|
ANSI A (Letter) | 8.5 x 11 | 215.9 x 279.4 |
Legal | 8.5 x 14 | 215.9 x 355.6 |
ANSI B (Ledger) | 11 x 17 | 279.4 x 431.8 |
ANSI B (Tabloid) | 17 x 11 | 431.8 x 279.4 |
Executive | 7.25 x 10.55 | 184.1 x 266.7 |
ANSI C | 22 x 17 | 559 x 432 |
ANSI D | 34 x 22 | 864 x 559 |
ANSI E | 44 x 34 | 1118 x 864 |
ISO A Paper Sizes
The A-series consists of a logical set of paper sizes that are defined by the ISO 216 standard. The largest size (A0) measures one square meter. The height/width ratio remains constant (1:1.41) for all sizes. This means you get the A1 size by folding an A0 paper in two along its shortest side. Then fold the A1 size in two to get an A2 size paper, and so on? A-sizes are used to define the finished paper size in commercial printing: A4 is for office documents, A5 is for notepads and A6 is for postcards.
Size | Inches | Millimeters |
---|---|---|
A0 | 33.125 x 46 | 841 x 1188 |
A1 | 23.375 x 33.125 | 549 x 841 |
A2 | 16.5 x 23.375 | 420 x 594 |
A3 | 11.75 x 16.5 | 297 x 420 |
A4 | 8.25 x 11.75 | 210 x 297 |
A5 | 5.875 x 8.25 | 148 x 210 |
A6 | 4.125 x 5.875 | 105 x 148 |
A7 | 2 x 4.125 | 74 x 105 |
A8 | 2 x 2 | 52 x 74 |
ISO B paper sizes
The same logic from the A-sizes also applies for the B-series, except here the starting point was the dimension of one of the sides, which starts at 1 meter. B-sizes are often used for posters.
Size | Inches | Millimeters |
---|---|---|
B0 | 39.37 x 55.67 | 1000 x 1414 |
B1 | 27.83 x 39.37 | 707 x 1000 |
B2 | 19.69 x 27.83 | 500 x 707 |
B3 | 13.90 x 19.69 | 353 x 500 |
B4 | 9.84 x 13.90 | 250 x 353 |
B5 | 6.93 x 9.84 | 176 x 250 |
B6 | 4.92 x 6.93 | 125 x 176 |
B7 | 3.46 x 4.92 | 88 x 125 |
B8 | 2.44 x 3.46 | 62 x 88 |
B9 | 1.73 x 2.44 | 44 x 62 |
B10 | 1.22 x 1.73 | 31 x 44 |
ISO C paper sizes
C-sizes are used for envelopes to match the A-series paper. I have omitted unrealistic sizes like C0 (imagine an envelope measuring 917 by 1297 millimetres).
Size | Inches | Millimeters |
---|---|---|
C2 | 25.51 x 18.03 | 648 x 458 |
C3 | 18.03 x 12.76 | 458 x 324 |
C4 | 12.75 x 9 | 324 x 229 |
C4 | 12.75 x 9 | 324 x 229 |
C5 | 6.375 x 9 | 162 x 229 |
C6 | 4.5 x 6.375 | 114 x 162 |
C7/6 | 3.5 x 6.5 | 89 x 165 |
ISO D paper sizes

Size | Inches | Millimeters |
---|---|---|
D0 | 42.91 x 30.35 | 1090 x 771 |
DL | 4.25 x 8.6.25 | 110 x 220 |
ISO RA & SRA paper sizes
These oversized papersizes are used by printers. The dimensions in millimetres are rounded to the nearest value.

RA2 | 24.02 x 16.93 | 610 x 430 |
Envelope Size Charts
Envelopes are available in many different colors, sizes and types of paper. They can even be custom-made if necessary, but this will add manufacturing time and cost to your project. It's a good idea to choose an envelope that is about ¼" larger than both the height and the width of the piece you are mailing. This allows for easy insertion but controls possible damage to the enclosure by minimizing excess space.
"A" Style Envelopes
These envelopes have a square flap. Some have deckle edges. Because they are available in many colors and finishes with matching text and cover papers, they are good choices for announcements, informal invitations, booklets, and brochures.
Name | Envelope Dimensions | Typical Enclosure Dimensions |
---|---|---|
A-2 | 4 ⅜ x 5 ¾ | 4 ⅛ x 5 ½ |
A-6 | 4 ¾ x 6 ½ | 4 ½ x 6 ¼ |
A-7 | 5 ¼ x 7 ¼ | 5 x 7 |
A-8 | 5 ½ x 8 ⅛ | 5 ¼ x 7 ⅞ |
A-9 | 5 ¾ x 8 ¾ | 5 ½ x 8 ½ |
A-10 | 6 x 9 ½ | 5 ¾ x 9 ¼ |
Slimline | 3 ⅞ x 8 ⅞ | 3 ⅝ x 8 ⅝ |
Baronial Envelopes | Business Announcements
These envelopes have a pointed flap. Baronial envelopes and cards are used primarily for formal business purposes. Matching enclosures can be ordered with or without a raised border panel.

5 Baronial | 4 ⅛ x 5 ½ | 3 ⅞ x 5 ¼ |

6 Baronial | 4 ¾ x 6 ½ | 4 ¼ x 6 ¼ |
Booklet Envelopes
Also known as "open-sided" envelopes, booklet envelopes are used in high volume mailings because they are machine insertable. They can be ordered with a self-sealing option, and in durable synthetic papers.
