ANSI C vs ANSI B

ANSI C is 152.4 mm wider and 127 mm taller than ANSI B. They are close but not interchangeable: a layout built for one clips or leaves a border on the other.

What Is Lost Printing One on the Other

At 100% scale, both centred, nothing resized. A positive figure on the wider or taller side is cropped; on the other it is a blank margin.

Frequently Asked Questions

Is ANSI C bigger than ANSI B?

ANSI C is bigger. It is 431.8 × 558.8 mm against 279.4 × 431.8 mm for ANSI B, about 2 times the area.

What is the difference between ANSI C and ANSI B?

ANSI C is 152.4 mm wider and 127 mm taller than ANSI B. They are close but not interchangeable: a layout built for one clips or leaves a border on the other.

Can you print ANSI B on ANSI C?

Not at full size without a change. Shrink ANSI B to 129% to fit ANSI C, which leaves a thin border, or print at 100% and lose 76.2 mm off each side and 63.5 mm top and bottom.
