1. What is the Picture Frame Cut Calculation?

The picture frame cut calculation determines the exact length to cut frame materials when accounting for mitered corners. This ensures perfect 45-degree joints when assembling the frame.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• Outer length — The visible length of the frame side
• Miter allowance — The additional length needed for the 45-degree cut at each end

Explanation: The equation accounts for material that will be hidden in the miter joint at both ends of each frame piece.

3. Importance of Accurate Cutting

Details: Precise cut lengths are crucial for creating perfect 45-degree miter joints that meet cleanly at the corners without gaps or overlaps.

4. Using the Calculator

Tips: Measure the outer length carefully, and know your miter allowance (typically the width of your frame material). Always double-check measurements before cutting.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine the miter allowance?
A: The miter allowance is typically equal to the width of your frame material. For example, if using 2-inch wide molding, the allowance is usually 2 inches.

Q2: Should I add extra length for mistakes?
A: It's often wise to cut pieces slightly longer (1/8" to 1/4") for test fitting, then make final precise cuts.

Q3: Does this work for all frame sizes?
A: Yes, the formula works for any rectangular frame size, from small photos to large paintings.

Q4: How important is precise measurement?
A: Extremely important - even 1/16" errors per side can compound to noticeable gaps in the corners.

Q5: Can I use this for frames with different width materials?
A: Yes, but you'll need to adjust the miter allowance accordingly for each piece if using different widths.
