Picture Frame Calculator – Measure Picture Frame Dimensions

This picture frame calculator is designed professionally to help you measure the correct frame size for your artwork or photographs.

It considers the dimensions of your image and the mat (if any) to calculate the appropriate frame size.

You have an 8×10 inch photo and want to add a 2-inch mat around it. The calculator would determine that you need a 12×14 inch frame to accommodate both the photo and mat.

Picture Frame Size Formula

The basic formula for calculating frame size is:

Frame Size = Image Size + (2 × Mat Width) + (2 × Frame Width)

For an 8×10 inch photo with a 2-inch mat and 0.5-inch frame:

• Width: 8 + (2 × 2) + (2 × 0.5) = 13 inches
• Height: 10 + (2 × 2) + (2 × 0.5) = 15 inches

You’d need a 13×15 inch frame.

How to measure Photo frame dimensions?

For a 5×7 inch photo with a 1.5-inch mat and 0.75-inch frame:

• Total width: 5 + (2 × 1.5) + (2 × 0.75) = 9.5 inches
• Total height: 7 + (2 × 1.5) + (2 × 0.75) = 11.5 inches

• Measure the image: Use a ruler to measure the width and height of your photo or artwork.
• Determine mat width: If using a mat, decide on its width (typically 1-3 inches).
• Consider frame thickness: Measure the width of the frame’s molding.
• Calculate total dimensions: Apply the formula above to determine the final frame size.
