Picture Framing Calculators
Free, practical tools for framing artwork and photos yourself — size your mat and frame, check a crop or print resolution before you order prints, weigh your glazing options, and hang the finished piece level and at the right height.
Mat Border Calculator
Work out the outer mat size and frame opening from your artwork size and desired border width — or go the other way and solve for an even border from a fixed frame.
Frame Size Calculator
Get the outer frame dimensions and molding length to buy from your artwork size, mat border width, and molding face width.
Aspect Ratio Calculator
Simplify any width/height pair to its ratio, and see the largest crop that fits your photo into a target print size like 8x10 or 4x6.
Print Resolution Calculator
Check the effective PPI of a photo at your intended print size, or find the minimum pixel dimensions needed to hit a target PPI like 300.
Glazing Weight Calculator
Estimate the weight of a sheet of glass or acrylic glazing from its size and thickness, and compare the two materials at the same dimensions.
Picture Hanging Calculator
Find the horizontal center and the exact hook height for a level, gallery-height hang, accounting for the drop from the frame's top to the taut wire.
