Enter the length and width of the picture into the calculator to determine the size of the picture frame; this calculator can also evaluate the length or width given the size of the picture frame is known.

Picture Frame Size Formula

The following formula is used to calculate the size of a picture frame:

S = 2L + 2W

Variables:

• S is the size of the picture frame
• L is the length of the picture
• W is the width of the picture

To calculate the size of the picture frame, multiply the length of the picture by 2, then add the result to the product of the width of the picture multiplied by 2.

What is a Picture Frame Size?

A picture frame size refers to the dimensions of the frame that will hold a picture or artwork. It is typically measured in inches or centimeters and is expressed as width by height. The size of the frame is determined by the size of the opening in the back where the picture or artwork is inserted, not the outer dimensions of the frame itself. For example, if a frame is listed as being 8″ x 10″, this means that the opening in the back of the frame is 8 inches wide and 10 inches tall, and it is designed to hold an 8″ x 10″ picture. The actual outer dimensions of the frame will be larger, depending on the width of the frame moulding. It’s important to note that the frame size should match the size of the picture or artwork to be framed, not the overall desired size including the frame.
