Canvas Size Calculator — Dimensions with Wrap
Calculate canvas fabric dimensions including gallery wrap allowance and stapling overlap.
Standard: 18mm or 38mm
How We Calculate This
Fabric dimension = Canvas dimension + (2 x wrap depth) + (2 x stapling allowance)
This adds wrap-around on all four sides. The visible painting area is canvas width x height, while total fabric includes all extra material.
