Choosing the right frame size should feel easy. We’re here to make it a little simpler.
This guide walks you through how sizing works, what happens when you add a mat, and a few details that can make a big difference when choosing the right frame.
How Frame Sizes Work
We list our frame sizes are based on the size of the art, photo, or print going inside the frame.
So, for example, a 3/4” wide frame:
- An 8x10 wall frame fits an 8x10 photo or print .
- The outside frame size is larger at 9" x 11"
The outside measurement changes depending on how wide the frame moulding is, but the listed frame size always refers to the artwork that goes inside.
Why the opening looks slightly smaller
But wait, the math isn’t right, you say! If I add ¾” width to 8x10, wouldn’t that be 9.5” x 11.5”?
Well, you may notice that the visible opening of a frame is a little smaller than the listed size. That is completely normal.
This is because every frame has a small lip around the inside edge that overlaps the artwork and helps hold it securely in place. That means a small portion of the edge of your artwork will sit beneath the frame. The standard lip is 1/4" on each side.
It is a small detail, but an important one, because it helps keep everything secure and looking clean.
What happens when you add a mat
Adding a mat allows you to frame artwork and photos that are smaller than the advertised frame size, but it doesn’t change the overall size of the frame.
For example:
- An 8x10 frame without a mat fits an 8x10 picture
- An 8x10 frame with a mat will fit smaller pictures. We offer two mat options, one for a 4x6 picture and one for a 5x7 picture
- The outside frame size stays the same
A mat gives the artwork a little breathing room and creates a more polished, finished look. We offer both physical mat boards and digital borders, depending on the product you choose.
Rabbet depth is the space inside the frame that holds the artwork, mat, glass, and backing. It’s a small detail, but an important one.
A deeper rabbet gives you more room inside the frame, which can be helpful for thicker paper, layered materials, or canvas.
It's important to note that our frames with a larger rabbet depth are not shadow boxes. With a shadow box, the backing sits farther behind the glass to create visible empty space inside the frame. Our frames are designed differently.
Why frame depth matters
Another detail that makes a difference is the outside frame depth.
At Frametolia, our frames are deeper than the average frame. That added depth gives the frame a more substantial, elevated look on the wall. It feels a little more custom, a little more finished, and adds to the overall presence of the piece.
It is not just about appearance, either. A deeper frame also allows for better support and more versatility, especially when framing pieces with added thickness.
It is one of those quiet details that makes the finished piece feel that much better.
A quick note on frame width
Frame width can really change the feel of a finished piece.
- Narrow frames feel clean and modern
- Medium-width frames are versatile and easy to style
- Wide frames feel more substantial and make a stronger statement
Larger artwork usually pairs best with a wider frame, while smaller photos and prints can feel more balanced with a narrower profile.
How to measure your artwork
The best way to choose your frame size is to measure the artwork itself.
A few simple tips:
- Measure width × height
- Measure the full piece edge to edge
- Do not round up or down
- Order the frame size that matches your artwork size
If you are adding a mat, just keep in mind that the visible opening will be smaller than the full size of the frame.

Sometimes numbers alone do not tell the whole story.
Measurements are hard to picture on a wall. Our interactive size guide lets you compare frame sizes and get a better sense of what will work in your space.
