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.

Size	Inches	Millimeters
SRA0	50.39 x 35.43	1280 x 900
SRA1	35.43 x 25.20	900 x 640
SRA2	25.20 x 17.72	640 x 450
SRA3	17.72 x 12.6	450 x 320
SRA4	12.6 x 8.86	320 x 225
RA0	48.03 x 33.86	1220 x 860
RA1	33.86 x 24.02	860 x 610
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.
