ANSI C Paper Size
ANSI C paper measures 17 × 22 in (431.8 × 558.8 mm). It is half an ANSI D sheet and four times the area of Letter, used for small assemblies and multi-view detail drawings.
ANSI C measures 431.8 millimetres wide and 558.8 millimetres tall.
ANSI C Dimensions in Each Unit
ANSI C is 431.8 × 558.8 mm, which is 43.2 × 55.9 cm or 17 × 22 in. It is ANSI D cut in half.

ANSI C to Scale
ANSI C is half of ANSI D and folds in half to ANSI B. One ANSI C sheet tiles into 2 × ANSI B, 4 × ANSI A. Put ANSI C next to another size in the comparison tool.
Frequently Asked Questions
What size is ANSI C paper?
ANSI C is 17 by 22 inches, or 431.8 by 558.8 mm, which is four Letter sheets in area.
How does ANSI C compare with A2?
A2 is 420 by 594 mm. ANSI C at 432 by 559 mm is slightly wider and shorter. Neither converts cleanly to the other.
What is ANSI C used for?
Small assembly drawings, wiring and connection diagrams, and reduced check prints of larger sheets.
Which is bigger, ANSI D or ANSI C?
ANSI D is the bigger of the two, at 558.8 × 863.6 mm against 431.8 × 558.8 mm for ANSI C. It has twice the area, so two ANSI C sheets cover one ANSI D.
