Calculate the correct paper size for an even photo border, compare common mat widths, and avoid measuring errors in scrapbook layouts.
SCRAPBUJOMeasure the actual printed photograph. Choose the visible border width. Add the border to both left and right. Add the border to both top and bottom.
A 1/16-inch border creates a fine line, 1/8 inch is subtle and practical, 1/4 inch creates clear separation, and wider mats can hold captions or decorative edges. Large patterns often need a wider neutral mat around the photograph.
Home and lab prints can vary slightly from their named dimensions. Measure with a ruler before cutting, especially when using borderless printing or photographs trimmed from a contact sheet.
Two mats can introduce an accent color and a neutral buffer. Keep the inner border narrow and allow the outer border to do most of the visual work. More than two layers often adds bulk without improving clarity.
