Framing Art with Borders or Signatures

Design a custom frame to perfectly suit your art

If you are framing artwork or a photo that has a border, signature or edition number, there are a few things to keep in mind.

Fortunately, you can achieve your desired results with online custom framing, all from the comforts of home!

In the following video and article below, we'll walk you through a few options and techniques you can use to design a custom frame that perfectly suits your art.


Frame It Without a Mat

The borders around an art print can serve the same role as matting, creating white space around the image that draws your eye towards the center.

The best way to frame artwork with a border

One option for framing artwork with a border like this is to simply frame the print without any matting.

The inside edges of the frame will overlap the paper by 1/4", but there should be plenty of border remaining, and of course, the full image or photo is visible.

You will just need to measure the full dimensions of the paper from edge to edge. If you are unsure about how to do this, we go through it step by step in our guide to measuring artwork like a pro.

Cover the Borders With a Mat

One way to preserve that border but enhance its effect is to add matting to your frame.

This gives you some flexibility on the mat color, and the beveled edges of the matting provide added depth and sophistication. Our matting is archival and acid-free, on par with the other conservation-grade materials we use in framing online.

In addition to the edge-to-edge dimensions of the paper, we'll need to measure the image size to go this route, which is just the printed image of your artwork.

Measuring image size and paper size for framing online

To cover the border completely, we will need to make the mat window almost the same size as the artwork, but it should be just a little smaller.

If our artwork is 6 x 6", the mat window should be 5-7/8" x 5-7/8". This ensures that the mat will slightly overlap the image without any gaps that would show the white of the paper.

Adding a mat to a custom frame

If your artwork is in between sizes, it's better to round down to the nearest 1/8" to prevent any space showing between the art and the mat.

Add a Mat and Preserve Part of the Border

Another common practice is using a mat inside the frame while still revealing some of the paper border.

This can be especially useful when your artwork has uneven borders you'd like to correct or if there is information in the margins you want to show.

It can also just create a nice double matting effect and extra visual elements around the artwork.

Adding a mat to the frame with a small border

To add a border like this for aesthetic reasons, you simply need the image size and the amount of paper you'd like to show between the image and the inside edge of the matting.

If the artwork is 6" x 6" and we want to reveal a small border around it, we will need to add that desired border width around each side of the image.

In this example, we take the image width of 6" and add 1/4" to the right and left sides, and then do the same vertically, adding 1/4" to the top and bottom. The most important thing is to make sure you don't forget to add the border twice.

So, for a desired paper border of 1/4" on each side of the image, we add 1/2" to the width and the height dimensions, giving us our mat window opening of 6-1/2" x 6-1/2".

Custom Mat Window Openings

Since the matting in our DIY custom frame kits will overlap the artwork dimensions you provide by 1/4" on each side, you will just add 1/2" to the width and height dimensions when inputting your dimensions to create a specific mat window opening.

Continuing with the example above of needing a 6-1/2" x 6-1/2" opening, we would input 7" x 7" to achieve the necessary window size when entering the artwork dimensions on our site.

Measure artwork for custom framing

And when building your custom frame on the next step using our frame visualizer, we show you exactly what the mat window opening will be, so it's a good idea to double-check this if you need a custom window size.

Design your frame online

Seeing the specs in real-time as you customize your frame is just one of the many reasons to go with online custom framing for your next project.

Note that if you are covering up, for example, 2" of the paper's border, you should add at least 2" of matting to the frame.

Otherwise, even though your mat window will reveal the artwork properly, the paper will not fit inside the frame and will need to be trimmed.

Framing Art with a Signature

When framing art with a signature or edition number in the border, we can use the same methods above to ensure that nothing is cut off or covered up.

If you are adding a mat, you will ultimately decide the border size and the resulting mat window opening based on how much space the signature needs.

Here, we'll first measure how much space we want to show below the image to accommodate that signature or edition number.

It appears that 5/8" of paper showing beneath the image and the inside edge of our mat will properly reveal and show off that signature and edition number.

Measuring an art print with a signature and edition number

For the mat window opening on this print, we now have two options:

1) Create an even border of 5/8" around each side of the image, or

2) Go with a narrower border - say 1/4", around the left, right and top of the image - and then the 5/8" of space below the image we need to accommodate that signature or edition number.


An even 5/8" paper border showing (left), and a bottom-weighted border (right).

In either case, to get your ideal mat window opening, you will add the desired left and right borders to each side of the image width and the desired top and bottom borders to each side of the image height.

And again, once you have your desired mat window opening add 1/2" to the width and height when entering your artwork dimensions on our site, double-checking that window opening in the frame visualizer to see exactly what you are getting.
