Custom Picture Mount FAQs
What is a mount (mat) and do I need one?
A mount is the border that sits between your artwork and the frame. It creates breathing space, prevents the image touching the glaze, and gives an elevated gallery look.
What sizes can you make for custom picture mounts?
We can make just about any size mount you need. The smallest mount we can make is 89mm x 89mm and the largest is 815mm x 1200mm.
Enter exact measurements in mm or choose from popular sizes. We cut every mount to order for a precise fit.
Can you make mounts for non-standard ratios and panoramic prints?
Absolutely. Enter your exact dimensions and we’ll build to fit. Our configurator supports long panoramic and uncommon formats.

How do I measure my artwork for a perfect fit?
Measure the exact image or paper size edge-to-edge. This is what you should input into the mount designer (Step 1).
We make the window slightly smaller so the edges overlap by 5mm. This helps to hold the artwork in place. Details on the very edge of your artwork may be cropped.
What file types and resolution do you accept?
We accept JPG and PNG. Aim for 300 dpi at the final print size (we advise a minimum of 200 dpi). Our custom frame designer tool will tell you if your file quality is suitable for the specific frame you're creating.
We accept no responsibility for the resulting print quality if the artworks supplied are low resolution/DPI or have been scaled up beyond their original size.
What happens if my upload isn’t large enough for the size I want?
In this case we recommend reducing the size of your frame, or adding a mount to keep the artwork smaller within a larger frame.
How will my order arrive?
Our mounts are carefully sandwiched between barrier boards for shipment. They will arrive in an envelope or box, depending on the size.
How long do custom picture mounts take to ship?
As everything is made to order, please allow 5 working days for us to create your custom mount
Need your custom mount sooner? We'll ship it the next working day if you select priority shipping at checkout.
Are your mounts conservation-grade?
Yes. Our mounts and backers are acid-free to help protect your artwork over time.
What if my mount arrives damaged?
Send us some photos of the damage and we will send you a free replacement, no questions asked.
Do you accept returns?
No, as our custom mounts are made bespoke for you we don't accept any returns.
Do you offer wholesale pricing?
Yes, we offer wholesale pricing for interior designers, commercial projects and anyone interested in purchasing our custom picture frames in bulk quantities. See more here.
