Picture Frame Length Formula:
| From: | To: |
The picture frame length calculation determines the total length of framing material needed to create a custom picture frame. This calculation accounts for both the dimensions of the artwork and any additional allowance needed for joining corners or overlapping.
The calculator uses the frame length formula:
Where:
Explanation: The formula calculates the perimeter of the artwork (2×(L+W)) and adds an allowance for miter cuts, overlaps, or joining mechanisms.
Details: Accurate frame measurement is crucial for creating professional-looking picture frames, minimizing material waste, and ensuring proper fit for the artwork. Precise calculations prevent gaps, overlaps, or misaligned corners.
Tips: Enter the artwork length and width in inches, plus any additional allowance needed for joining. All values must be positive numbers. Typical allowance ranges from 0.25-0.5 inches depending on the joining method.
Q1: What is the purpose of the allowance in frame calculation?
A: The allowance accounts for the material that will be used in joining the corners, whether through miter cuts, overlapping, or other joining techniques.
Q2: How much allowance should I typically use?
A: For standard mitered corners, 0.25-0.5 inches is typically sufficient. The exact amount depends on the frame material thickness and joining method.
Q3: Does this calculation work for oval or circular frames?
A: No, this formula is specifically for rectangular frames. Oval and circular frames require different calculations based on their circumference.
Q4: Should I include the mat board in my measurements?
A: No, this calculation is for the frame itself. You should measure the outer dimensions of the artwork including any matting.
Q5: Can I use this for frames with different widths on different sides?
A: This formula assumes uniform frame width. For frames with varying widths, you would need to calculate each side separately and sum them.
