Frame It Right: Calculate Picture Frame Size the Easy Way!
Choosing the right frame size can be tricky. Too small, and your artwork feels cramped. Too large, and it can overwhelm the piece. This guide will help you easily calculate picture frame size for a perfectly balanced display.
Understanding the Basics
Before we dive into calculations, let’s define the key terms:
- Artwork Size: The actual dimensions of your picture, photograph, or painting.
- Frame Size: The inside dimensions of the frame, which should closely match your artwork size.
- Matting: The decorative border placed between the artwork and the frame.
- Rabbet: The inner lip of the frame that holds the artwork, matting, and glazing (glass or acrylic).
Step 1: Measure Your Artwork Accurately
This seems obvious, but it’s crucial. Use a ruler or measuring tape to get precise measurements of the height and width of your artwork. Measure to the nearest eighth of an inch (or millimeter, if you prefer).
- If your artwork has irregular edges, measure the widest and tallest points.
- For mounted artworks, measure the entire mounted piece, not just the visible image.
Step 2: Decide if You Want Matting
Matting adds visual appeal and can protect your artwork. It creates a "breathing space" that enhances the presentation.
- No Matting: If you prefer a minimalist look, your frame size should match your artwork size.
- With Matting: You’ll need to factor in the mat width when calculating the frame size.
Step 3: Calculating Frame Size with Matting
This is where we really calculate picture frame size. We’ll use a simple formula:
Frame Size = (Artwork Width + (Mat Width x 2)) x (Artwork Height + (Mat Width x 2))
Determining the Mat Width
The ideal mat width depends on the size of your artwork:
- Small Artwork (under 8×10 inches): 1.5 – 2 inch mat width
- Medium Artwork (8×10 to 16×20 inches): 2 – 3 inch mat width
- Large Artwork (over 16×20 inches): 3 – 4 inch mat width (or larger, depending on the artwork)
These are just guidelines. Consider the artwork’s style and your personal preference. A wider mat can make a bold statement, while a narrow mat is more subtle.
Example Calculation
Let’s say you have an 8×10 inch photograph and want a 2-inch mat.
- Artwork Width: 8 inches
- Artwork Height: 10 inches
- Mat Width: 2 inches
Applying the formula:
- Frame Width: 8 + (2 x 2) = 8 + 4 = 12 inches
- Frame Height: 10 + (2 x 2) = 10 + 4 = 14 inches
Therefore, you would need a 12×14 inch frame.
Step 4: Accounting for the Rabbet Depth
The rabbet is the groove on the inside edge of the frame that holds the artwork, matting, and glazing. Ensure the rabbet depth is sufficient to accommodate all the layers.
- Check the Rabbet Depth: When purchasing a frame, always check the rabbet depth specification.
- Sufficient Depth: Make sure the depth is greater than the combined thickness of your artwork, matting, and glazing. This is especially important if your artwork is mounted on a thick board.
Step 5: Choosing the Right Frame Style
While not directly related to calculate picture frame size, the frame style significantly impacts the overall look. Consider the following:
- Artwork Style: Match the frame style to the artwork’s aesthetic. A modern photograph might look great in a sleek, minimalist frame, while a classic painting might benefit from an ornate, traditional frame.
- Room Décor: Choose a frame that complements your room’s color scheme and overall style.
- Frame Material: Wood frames are classic and versatile, while metal frames offer a more contemporary look. Consider the durability and maintenance requirements of different materials.
Quick Reference Table: Frame Size Calculation with Matting
Artwork Size (inches) | Recommended Mat Width (inches) | Frame Size (inches) |
---|---|---|
5×7 | 1.5 | 8×10 |
8×10 | 2 | 12×14 |
11×14 | 2.5 | 16×19 |
16×20 | 3 | 22×26 |
This table provides a quick reference. Always double-check your measurements and consider your personal preferences.
Frequently Asked Questions: Calculating Picture Frame Size
Here are some common questions about calculating picture frame size accurately, so you can frame your artwork like a pro.
What’s the simplest way to calculate the right picture frame size?
Start by measuring the exact height and width of your artwork. Then, decide how much of the artwork you want to be visible within the frame’s opening. This visible area is your "artwork sight size". Finally, the frame size you order or build should match that artwork sight size.
Why is it important to precisely calculate picture frame size?
Accuracy is key! A frame that’s too small will cut off part of your artwork, while a frame that’s too large will leave unsightly gaps. Taking the time to calculate picture frame size correctly ensures a professional and aesthetically pleasing result.
Do I need to add extra space when I calculate picture frame size?
No, the frame size you specify should be the exact size of the opening in the back of the frame (where the artwork sits). Don’t add extra space unless you specifically want a gap between the artwork and the frame’s rabbet.
What if my artwork isn’t a perfect rectangle? How do I calculate picture frame size then?
For irregular shapes, measure the widest and tallest points of the artwork. Use these measurements to determine the minimum frame size needed to display the entire piece. You might need to adjust the visible area for the best visual fit.
So, there you have it! Now you’re ready to calculate picture frame size like a pro. Go forth and frame with confidence!
