How to Measure the Perfect Frame for Your Artwork

If you have ever wondered how to measure a photo frame or struggled to get the right fit for your artwork, you are not alone. This photo frame measurement guide will walk you through everything you need to know about choosing custom photo frames that fit perfectly—without stress, confusion, or costly mistakes.

Why Measuring Matters More Than You Think

Let’s be honest—measuring sounds simple. You grab a ruler, jot down some numbers, and done… right?

Not exactly.

When it comes to framing, even a small mistake (like 1/8 of an inch) can mean your artwork doesn’t fit, shifts inside the frame, or gets covered in ways you didn’t expect.

Think of your frame like a tailored suit. If it’s too tight, it won’t fit. Too loose, and it just looks off.

That’s why understanding how to measure a photo frame properly is the difference between “good enough” and “perfect.”

Step 1: Start With Your Artwork (Not the Frame)

Here’s the biggest mistake people make: they measure the frame first.

Instead, always start with your artwork.

What You Actually Need to Measure

You want the visible image area, not necessarily the full paper size.

For example:

●You print an 8×10 photo on 8.5×11 paper

●The actual image is still 8×10

That means your frame size should be based on 8×10—not the paper.

How to Measure It (The Easy Way)

●Lay your artwork flat on a table

●Use a rigid ruler (not a soft tape)

●Measure left to right→ this is your width

●Measure top to bottom→ this is your height

Write it like this:

Width × Height (W × H)

Example: 8 × 10 inches

Simple, right?

Step 2: Decide What You Want to Show (Borders or No Borders)

Now here’s where things get a little more personal.

Some photos have white borders, signatures, or extra space around the edges.

So you need to ask yourself:

Do you want to see that border, or hide it?

Option A: Show the Border

Measure the entire piece, including the border.

Option B: Hide the Border

Measure only the image area.

If you’re using a mat (which we’ll cover next), it will cover the edges cleanly.

Step 3: Understanding Mat Boards (And Why They Change Everything)

If you’ve ever looked at a frame and noticed a nice white border around the photo—that’s a mat.

Mats do two things:

●Make your artwork look more premium

●Change the size of the frame you need

Here’s the Key Idea

When you add a mat:

Your frame gets bigger, but your image size stays the same

Example

●Artwork: 8×10

●Frame with mat: 11×14

That’s because the mat fills the extra space.

Important Detail: The Mat Opening

The opening in the mat is usually slightly smaller than your image.

Typical overlap:

●About 1/4 inch on each side

So for an 8×10 image:

●Mat opening might be 7.5 × 9.5

This keeps your photo from falling through and holds it in place.

Step 4: What Frame Size Really Means (This Confuses Everyone)

Let’s clear this up once and for all.

When a frame is labeled:

👉 11 × 14

It refers to the inside dimensions—not the outside.

And here’s the twist:

The actual opening is usually slightly larger (about 1/8 inch) to allow everything to fit comfortably.

So What Should You Choose?

●No mat?Choose a frame that matches your artwork size

●With mat?Choose a frame that matches the mat’s outer size

This is a core part of any solid frame size really means.

Step 5: Don’t Forget Frame Depth (Especially for Canvas)

If you’re framing something thicker—like a canvas—this step matters a lot.

What Is Frame Depth?

It’s how deep the frame is from front to back.

You need enough depth to hold:

●Your artwork

●Glass or acrylic (if used)

●Backing board

How to Measure Depth

Measure from:

●The front surfaceof your artwork

●To the very back

Example:

●Canvas depth = 1 inch

You’ll need a frame that can handle that thickness.

Step 6: Understand Rabbet Depth (The Hidden Detail)

This is one of those terms that sounds strange—but it’s important.

The rabbet is the groove inside the frame where everything sits.

Why It Matters

If the rabbet is too shallow:

●Your artwork won’t fit

●Or the backing won’t close properly

General Rule

●3/8 inch rabbet → works for most standard setups

●Deeper rabbet → needed for mats or thicker artwork

Step 7: Outside Frame Size (For Wall Planning)

Sometimes it’s not about the artwork—it’s about your wall space.

The outside dimensions tell you how big the frame will look on your wall.

Example

An 11×14 frame might actually be:

●14 × 17 overall

Why?
Because of the frame thickness.

So if you’re planning a gallery wall, this measurement is key.

Step 8: Measuring Like a Pro (Small Tips That Make a Big Difference)

Here are a few practical tips that will save you headaches:

✔ Always Measure Twice

Even if the size is “standard,” double-check it yourself.

✔ Use Inches (Not Mixed Units)

Switching between cm and inches is a common mistake.

✔ Round Up Slightly

A tiny bit of extra space is better than a tight fit.

✔ Use a Rigid Ruler

Soft tape can bend and throw off your measurement.

✔ Write It Clearly

Always record sizes like this:

Width × Height × Depth

Step 9: Common Mistakes to Avoid

Let’s save you from the most common framing regrets.

❌ Measuring the Old Frame Instead of the Artwork

Frames can vary—your artwork is the only constant.

❌ Ignoring Mat Overlap

That 1/4 inch can cover important details.

❌ Forgetting Depth

Especially for canvas or mounted pieces.

❌ Rounding Down

This often leads to a frame that’s too tight.

Step 10: Choosing Custom Photo Frames (The Smart Way)

Now that you understand how to measure a photo frame, choosing the right one becomes much easier.

Custom photo frames are ideal when:

●Your artwork isn’t a standard size

●You want a specific look

●You’re working on a brand or commercial display

●Measure your artwork (not the paper)

●Decide if you want a mat

●Choose frame size based on artwork or mat

●Check depth for thicker pieces

●Double-check everything

That’s it.

Once you understand these basics, framing becomes a lot less confusing—and honestly, kind of satisfying.

Final Thoughts
