The Picture Frame Molding Calculator simplifies this process by allowing you to input the picture dimensions, molding width, and waste factor.
Formulas for Picture Frame Molding Calculations
1. Total Frame Dimensions
To determine the total dimensions of the frame, the molding width is added to both sides of the picture width and height:
Total Width=W+2×MTotal Height=H+2×M
Where:
- W = Picture width (in inches or cm)
- H = Picture height (in inches or cm)
- M = Molding width (in inches or cm)
Example Calculation for Frame Dimensions
Input Values:
- Picture Width (W) = 12 inches
- Picture Height (H) = 8 inches
- Molding Width (M) = 1 inch
Using the formulas:
Total Width=12+2×1=12+2=14inTotal Height=8+2×1=8+2=10in
2. Total Molding Length Needed
The total molding length for a single frame is calculated by summing all four sides of the frame:
L=2×(Total Width+Total Height)
Where:
- L = Total molding length for one frame (in inches or cm)
- Total Width = Total width of the frame (calculated above)
- Total Height = Total height of the frame (calculated above)
Example Calculation for Total Molding Length
Input Values:
- Total Width = 14 inches
- Total Height = 10 inches
Using the formula:
L=2×(14+10)=2×24=48in
3. Total Molding Length with Waste Factor
To account for cutting errors and material waste, a waste factor is added to the total molding length:
Ltotal=L×(1+F)
Where:
- Ltotal = Total molding length including waste factor (in inches or cm)
- L = Total molding length (calculated above)
- F = Waste factor (as a decimal, e.g., 10% = 0.1)
Example Calculation for Total Molding Length with Waste Factor
Input Values:
- Total Molding Length (L) = 48 inches
- Waste Factor (F) = 10% = 0.1
Using the formula:
Ltotal=48×(1+0.1)=48×1.1=52.8in

FAQ
Q: What is picture frame molding?
A: Picture frame molding is decorative trim used to create a frame around a picture, photograph, or other artwork. It comes in various materials, profiles (shapes), and finishes.
Q: What are the different types of picture frame molding materials?
A: Common materials include:
- Wood: The most popular choice, offering versatility in styles and finishes. Common wood types are pine, poplar, oak, and maple.
- MDF (Medium-Density Fiberboard): An engineered wood product that is smooth, consistent, and less expensive than solid wood.
- Polystyrene (Plastic): A lightweight and affordable option, often used for pre-made frames.
- Metal: Used for a more contemporary look, typically aluminum or steel.
Q: What is the difference between the molding width and the frame width?
A: The molding width refers to the width of the molding itself (how much of the molding face you see). The frame width is the total width of the finished frame, including the molding and the picture.
Q: How do I measure for picture frame molding?
A: Measure the width and height of your artwork. Then, add twice the width of the molding to both the width and height of the artwork to determine the outer dimensions of the frame.
Q: How do I calculate how much molding I need?
A: Once you have the outer dimensions of the frame (width and height), use the following formula:
Total Molding Length = 2 * (Frame Width + Frame Height)
Q: What tools do I need to cut picture frame molding?
A: Essential tools include:
- Miter saw or miter box: For making accurate miter cuts.
- Measuring tape or ruler: For precise measurements.
- Pencil: For marking cuts.
- Safety glasses: For eye protection
