About this app
MatBorderCalc is a simple utility for artists, photographers, framers, and printmakers who need accurate mat border measurements. Enter the mat size and image size, choose a mat overlap, choose inches or centimeters, and MatBorderCalc calculates the top, bottom, and side borders to cut. Use equal borders for centered placement, or add an extra top or bottom offset when a composition needs a slightly different visual balance. Features: - Calculate top, bottom, and side mat borders - Inches and centimeters - Inch fractions in sixteenths - Mat overlap picker from -1 to +1 inch in 1/16 inch increments - Centered layout when no offset is selected - Optional top or bottom offset - Offset amount automatically disabled when no offset is selected - Offset resets to zero when switching back to None - Compact iPhone layout with keyboard Done button - Selects measurement text automatically when editing - Runs on iPhone, iPad, and Mac with Mac Catalyst - No account, tracking, ads, analytics, or network requirement MatBorderCalc keeps the workflow direct: enter dimensions, choose the amount of mat overlap or white reveal, choose an offset if needed, and cut from the displayed border measurements.
