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

ISO RA & SRA paper sizes

These oversized papersizes are used by printers. The dimensions in millimetres are rounded to the nearest value.

Size Inches Millimeters
SRA0 50.39 x 35.43 1280 x 900

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.
