Learn how to cut picture mats for oversized mat frames. Using a picture mat cutter you can change the size or color to make your own custom picture mats!

I’m shooting you straight here before you dive in to learning how to cut a frame mat, this project is definitely doable as a DIYer but you’ll need to practice a few times to get the hang of it. It’ll save you lots of money on large matted frames though, so buckle up and learn. You’ll thank me, later!

Adding Custom Picture Frame Mats to our Hallway

When I set out to add travel photos to my hallway, I knew that the project could get really pricey, really fast.

I priced out large matted frames for the hallway remodel and each option came up to over $120 per frame. I knew I wanted at least five frames so $600+ for a gallery wall was not going to cut it.

After quite a bit of research about what to DIY or how to DIY part of this project, I decided on buying a picture mat cutter and the rest is history. =)

Supplies Needed to Cut Custom Mat for Frame

• Belmont 24×36″ Frame – Honey  (these go on sale for $16 quite frequently)
• 24″ by 36″ White Mat board – In store at Michaels for around $8
• Photo Mat Cutter
• Level or other straight edge
• Razor blade
• Photo – For irregular, large sizes, Nations Lab does a GREAT job and I’ve found them to be the most affordable.
• Cardboard (to protect your floor)
• Extra set of hands (you need one person to hold the level and another to use the cutter)

Cutting a Custom Mat for Frame

1. Have your photo printed to the size you want. For my project, I printed a 15.5 x 15.5 square photo.

2. Practice cutting with the mat board cutter on scraps of mat board.

3. Take your photo and place it on top of the back of the mat board to visualize where you want to cut your mat board. *

4. For my 15.5″ square photo, I knew I wanted my photo centered from left to right but offset from the top to the bottom.

5. I went with 4.25″ on left and right as well as the top. Using a straight-edge, draw lines to create your cutting pattern (which is essentially the frame around the photo) on the back side of the mat board.

6. Using the straight edge as a guide, firmly press down on your mat board cutter and start cutting. When you get to the end of the line, stop about 1/4″ from the end so your cut line doesn’t show through the mat board once you flip it over.

7. Work on your cuts in a clockwise motion.

8. Gently tap out the cut mat board. You can use a razor to help clean up any stray pieces.

* We have done this process quite a few times now and tend to do it a bit differently, now. We’ve found it easier to trace the photo shape on the front of the mat board. You’ll actually want to draw something a tiny bit smaller than the photo on the front of the mat board. Then, you’ll cut the board from the front. This makes lining up the corners easier and makes the whole process a little less error-prone.

Cost Savings For Cutting Your Own Custom Picture Mats

Each of the custom picture mats took us about 15 min per mat (after the first one). I ended up with five large matted frames for my hallway remodel with a total cost, out of pocket, of $40 per frame.

The cost of picture frames and matting goes with the size. The frame that I used was 24×36 so it’s definitely a large frame. By cutting my own photo mat board, I definitely saved money but if you have small square frames with a mat… the cost savings would be less.

In a big box store near me, I was quoted $50 per frame mat. For my 24×36’s frames, that would have been over $250 for all the photo frame mats alone.

It’s by far the cheapest to use pre-cut frame mats but those are usually only available in standard sizing and in standard cuts (such as a 5×7 mat board for a 8×10 frame).

For a totally custom look, I’d definitely suggest investing in a picture frame mat cutter and learning how to cut frame mats yourself!
