How to Measure Picture Frame Sizes for Your Art or Photo

how do you measure a picture frame

Hi, I’m Evlyn from Frame Destination. Many people ask us about picture frame sizes, such as how to measure them, what the size means, and how to ensure your art or photo fits just right. If you’re an artist, decorator, or DIY framer, knowing how to measure frames is essential for showing off your artwork. Here’s how to get the perfect fit.

Understanding Picture Frame Measurements

When you buy a frame or prepare to frame your art, it’s essential to know which measurements to use. The size of a picture frame is based on its inside dimensions, which indicate the size of the art or photo that can fit inside. To make sure everything fits well, measure both your artwork and the frame carefully.

Choosing the Right Measuring Tool

To get accurate measurements, start with the right tool. A regular tape measure works, but a contractor’s tape measure is even better because it’s sturdy and easy to use. You can also use a wooden ruler or an architect’s flat ruler for precise results. A tailor’s tape can also work, but it’s more challenging to keep flat and straight. Whatever you choose, ensure it lies flat for optimal accuracy.

How to Read a Ruler or Measuring Tape

Measuring tapes and rulers show fractions, which help you measure more precisely. The marks between inches stand for fractions like one-sixteenth or one-eighth of an inch. Pay attention to these details when measuring. For example, if your item is two marks past the three-inch line, it measures 3 1/8 inches.

Step-by-Step Guide for Measuring Art

  1. Measure the Artwork’s Dimensions:
  2. Begin by measuring only the artwork, not the surrounding paper. For example, if you have an 8×10 photo, measure only the image, not any extra paper. Check the width from left to right and the height from top to bottom.
  3. Include or Exclude the Border:
  4. If your art has a border you want to keep, include it in your measurements. For example, if you prefer having a border around your image, measure the artwork with the border included. If you only want part of the border to show, adjust your measurements accordingly.
  5. Account for Depth:
  6. If your art is three-dimensional, such as a canvas painting or textile, measure its thickness as well. This matters when you use a frame with a rabbet, which is the groove that holds the art. Thicker art may need a deeper frame.

Frame Size vs. Art Size

Frame sizes are typically named for the size of the art they accommodate, such as 8 x 10 or 11 x 14. (Frame Your World: Mastering the Art of Frame Size Selection, n.d.) Most frames are slightly larger than the listed size, allowing the glass, mat, and backing to fit inside. (Frame Types, n.d.) When ordering a frame, measure the inside space where the art will be displayed, not the outside dimensions of the frame.

Frames with Mats: Understanding Mat Dimensions

If you want to add a mat around your art, you’ll need two measurements: the mat’s opening and its outside size. The opening is the hole in the mat, and the outside size is the mat’s complete edge-to-edge measurement. For example, an 8×10 photo with a mat might have a 7 ½ x 9 ½ inch opening so the mat slightly covers the photo.

If you choose a mat with a border, such as a 3-inch mat, double the width and add it to your artwork’s size. For example, a 3-inch mat adds 6 inches to both the width and height, so your frame will need to be bigger.

The Role of the Rabbet

The rabbet is the groove in the frame that holds your art, mat, and other parts. Ensure the rabbet is deep enough to accommodate your artwork and mat. Most rabbets are 3/8 inch deep, but you can find deeper ones for thick art or extra mats. (48 x 16 Open Picture Frames With 0.5000 Rabbet Depth, n.d.)

Final Tips for Accurate Measurements

  • Always measure from the zero mark of your ruler or tape measure.
  • Use inches for measurements, as U.S. framing standards typically use inches. (Framing 101: Understanding Standard Frame Sizes and How to Measure Them, n.d.)
  • Write down your measurements as you go, whether on paper or a digital device.
  • Include the correct thickness for three-dimensional pieces to ensure the frame can accommodate them.
  • When in doubt, round up to the nearest fraction if you’re between measurements.

Choosing the Perfect Frame

Once you’ve measured your art and selected a mat, you can then choose your frame style and color, if desired. Please enter your measurements on the framing website or share them with our customer service team to ensure the right fit.

Conclusion

Measuring your art for a frame may seem tricky, but with the right tools and some care, you can find the perfect frame to showcase your work. Whether it’s a photo or a canvas, knowing your measurements helps you get a polished, professional look. Now, frame your beautiful art!

Key Takeaways:

  • Use a contractor’s tape measure or a wooden ruler for accuracy.
  • Measure the width and height of your artwork, excluding any unwanted borders or margins.
  • When using a mat, account for its border and the frame’s interior dimensions.
  • The rabbet depth of the frame is crucial for fitting thicker pieces of wood.
  • Always measure the frame’s inside dimensions and double-check the size for mats.

By using these tips, you can measure for a frame that fits your art or photo perfectly, helping it look its best.
