1. What is Picture Frame Perimeter?

The perimeter of a picture frame is the total length of framing material needed to go around the picture. It accounts for both the length and width of the picture plus any additional material needed for mitered corners.

2. How Does the Calculator Work?

The calculator uses the picture frame perimeter formula:

Where:

• \( Length \) — Longest side of the picture (inches)
• \( Width \) — Shortest side of the picture (inches)
• \( Miter\ Allowance \) — Additional length needed for corner joints (inches)

Explanation: The formula calculates the total length needed by adding up all sides and accounting for material lost in mitered corners.

3. Importance of Accurate Measurement

Details: Precise perimeter calculation ensures you purchase the correct amount of framing material and helps avoid costly mistakes in custom framing projects.

4. Using the Calculator

Tips: Measure your picture's length and width in inches. Include the miter allowance (typically 0.25-0.5 inches per corner). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is miter allowance?
A: Extra length needed for corner joints where material is cut at 45° angles. Typically 0.25-0.5 inches per corner.

Q2: How do I measure my picture?
A: Measure the longest side (length) and shortest side (width) of the visible image area you want to frame.

Q3: Should I include the frame width in calculations?
A: No, this calculates the inner perimeter. For outer frame dimensions, add twice the frame width to each side.

Q4: What's typical miter allowance?
A: For standard frames, 0.5 inches total (0.125 inches per corner) is common. Larger frames may need more.

Q5: Can this be used for oval frames?
A: No, this is for rectangular frames only. Oval frames require different calculations.
