Picture Frame Calculator

Find the frame size after adding a mat around your art.

How the Math Works

The Picture Frame Calculator uses a simple yet powerful formula: frame = print + 2×mat. This equation takes the dimensions of your picture print and adds twice the mat width to each side, accounting for the border on both left and right (or top and bottom). For example, if your print is 8 inches wide and you want a 2-inch mat border, the total frame width would be 8 + (2×2) = 12 inches. The multiplication by two ensures the mat is added equally to both sides of your image.

Practical Applications

To use this calculator practically, first measure your picture print's dimensions accurately. Next, determine how wide you want your mat border to be - typically 1-3 inches works well for most photos. Multiply your desired mat width by two, then add this to your print's measurement. This gives you the exact frame size needed, ensuring your mat sits perfectly within the frame without gaps or overlaps.

Day-to-Day Use

This calculator saves you time and money when framing photos for your home, office, or gifts. Instead of guessing and potentially buying an incorrectly sized frame, you can quickly determine the perfect fit. Whether you're creating a gallery wall, framing a wedding photo, or preparing artwork for sale, this tool eliminates the frustration of returns or ill-fitting frames, helping you achieve a professional, polished presentation every time.
