ANSI B Paper Size
ANSI B paper measures 11 × 17 in (279.4 × 431.8 mm). It is two Letter sheets side by side and identical to Tabloid or Ledger, used for spreads, spreadsheets and small engineering drawings.
ANSI B measures 279.4 millimetres wide and 431.8 millimetres tall.
ANSI B Dimensions in Each Unit
ANSI B is 279.4 × 431.8 mm, which is 27.9 × 43.2 cm or 11 × 17 in. It is ANSI C cut in half.
| Unit | Width | Height | Width × height | Copy |
|---|---|---|---|---|
| Millimetres (mm) | 279.4 | 431.8 | 279.4 × 431.8 mm | |
| Centimetres (cm) | 27.9 | 43.2 | 27.9 × 43.2 cm | |
| Metres (m) | 0.279 | 0.432 | 0.279 × 0.432 m | |
| Inches (in) | 11 | 17 | 11 × 17 in | |
| Feet (ft) | 0.92 | 1.42 | 0.92 × 1.42 ft | |
| Points (pt) | 792 | 1224 | 792 × 1224 pt | |
| Picas (pc) | 66 | 102 | 66 × 102 pc | |
| Pixels at 72 DPI | 792 | 1224 | 792 × 1224 px | |
| Pixels at 150 DPI | 1650 | 2550 | 1650 × 2550 px | |
| Pixels at 300 DPI | 3300 | 5100 | 3300 × 5100 px | |
| Pixels at 600 DPI | 6600 | 10200 | 6600 × 10200 px |
Pixel counts follow from the resolution: pixels = millimetres ÷ 25.4 × DPI. More on the DPI and pixels page.

ANSI B to Scale
ANSI B is half of ANSI C and folds in half to ANSI A. One ANSI B sheet tiles into 2 × ANSI A. Put ANSI B next to another size in the comparison tool.
Frequently Asked Questions
Is ANSI B the same as Tabloid?
Yes. ANSI B, Tabloid and Ledger are all 11 by 17 in. Tabloid usually means the portrait orientation and Ledger the landscape one; ANSI B is the engineering name.
Is ANSI B related to ISO B4 or B5?
No. The ISO B series is a separate metric standard based on the √2 ratio. ANSI B is simply two US Letter sheets and shares only the letter.
What is ANSI B used for?
Printed spreadsheets, two-page design proofs, and the smallest engineering drawings that still need a title block.
Which is bigger, ANSI C or ANSI B?
ANSI C is the bigger of the two, at 431.8 × 558.8 mm against 279.4 × 431.8 mm for ANSI B. It has twice the area, so two ANSI B sheets cover one ANSI C.
