Banner Flat Size Calculator
Enter finished size plus the finishing allowances that will fold behind the face.

Geometry is only one part of a large-format job
These tools calculate flat size, paneling, roll usage, finishing geometry or cost. Wind loading, structural attachment, fire/building requirements, media suitability and installer safety are outside the calculator and should be verified for the actual installation.
What the result is useful for
Useful before artwork/media planning so hems and pockets are not accidentally taken from the visible finished face.
How the calculation works
Flat width = finished width + left/right finishing allowances. Flat height = finished height + top/bottom finishing allowances.
What this calculator cannot know
Finishing construction varies by banner material and shop. Enter the actual allowance supplied by the fabricator.
