Measuring advice

Everything we make is cut to the size you enter. Pick what you're framing below and we'll show you exactly what to measure.

Measure twiceCustom-made items can't be refunded or exchanged, so please check every measurement before you order.

What are you framing?

A photo or print, edge to edge

Measure the exact outside width and height of the print.

The frame or mount overlaps the edges by a few millimetres, so nothing falls through.

Measure along the dashed line.

What we make from your size

Enter your artwork size to see how each product works around it. Sizes are approximate, and a few millimetres either way is normal.

If you orderYou enterWe makeWhy
A frame with a mount250 x 190mmMount opening 244 x 184mmThe opening overlaps your artwork by 3mm on each side so it can't fall through. The frame size depends on the border widths you choose.
A mount only250 x 190mm plus border widthsMount opening 244 x 184mmThe outside size of the mount should match the opening of the frame it is going into: check the External Mount Size on your order review.
A frame with no mount250 x 190mmFrame opening about 252 x 192mm to 254 x 194mmThe opening is 2 to 4mm larger to allow a little movement, and the lip of the frame overlaps the artwork by about 5mm on each side.
A canvas floater frame250 x 190mm (your canvas)Front opening about 260 x 200mmThe default shadow gap leaves 5 to 6mm on each side. Without it, the opening is 2 to 4mm larger. Check the frame's internal depth against your canvas.
A canvas picture frame250 x 190mm (your canvas)Rear opening a few mm largerThe canvas loads from the back, with a little room to move. Supplied without glazing or backing.
An inset frame250 x 190mm (your canvas board)Front opening a few mm largerThe board drops into the front opening, with a small movement allowance.
Canvas stretcher bars250 x 190mmOutside size 250 x 190mm, within 0 to 2mmThis is the size of the finished stretcher. Allow extra canvas to wrap round it.

Want the mount opening cut to exactly the size you enter, with no overlap? Choose "Cut aperture the exact size" under the advanced options when you order.

Three habits that prevent mistakes

Use a metal tape measureNot a fabric tape or a ruler. How to use one accurately
Measure twice, write it downCheck each side, then note everything on paper before you start ordering.
Measure the artwork yourselfNever rely on sizes listed on packaging or on another website.

Watch how to measure

The detail, by what you are ordering

I am ordering a picture frame without a mount

Enter your artwork size into our website and select a suitable picture frame.

We would manufacture your frame so artwork measuring the size entered will fit into the opening at the back of the frame.

So if your artwork measures 320 X 470mm, you would enter 320 X 470mm as your frame size - Easy!

* The actual opening size of the frame will be approx 2-4mm bigger than the stated size to allow for a small amount of movement.
** The lip/rebate of the frame will overlap the artwork by approximately 5mm on each side.

I am ordering a picture frame with a mount

Enter your artwork size into our website and select a suitable picture frame and mount combination.

So if your artwork measures 250 X 190mm, you would enter 250 X 190mm in the size fields. We would manufacture the mount with an actual aperture of 244 X 184 so that it justs overlaps the image to allow it to be positioned correctly.

If you do not want us to make our standard 3mm adjustment on the border widths you can select the 'Cut aperture the exact size' advanced option during the order process. Doing so will mean the opening will be cut to the exact artwork size specified.

The frame size will be calculated by our software and depends on how wide you set the mount borders.

I am ordering a picture mount without a frame

If you are purchasing a mount to fit a frame bought elsewhere you need to know the frame size(the glazing/backing size) of your current frame as well as the size of your artwork.

Simply enter the exact sizes of your artwork into the internal size fields. You then have the option to enter the width for each side of the mount, top, bottom, left and right. You will need to calculate manually how wide the mounts need to be to fit your frame opening size.

Please ensure the "External Mount Size" measurements on your order review match the actual opening size of your own frame from the back.

We will make a small 3mm adjustment to each mount width to ensure the artwork doesn't fall through the middle of the mount aperture.. So if you artwork measures 250 X 190mm, you would enter 250 X 190mm in the size fields, we would manufacture the mount so the actual aperture would be 244 X 184. This ensures the artwork doesn't fall through the mount opening.

I am ordering a canvas floater frame

You should enter the exact width and height of your canvas into our website. The default option is for a canvas floater frame to include a 5-6mm shadow gap on each side between the frame and your canvas. This means the actual opening size at the front of the canvas floater frame will be approximately 10mm larger than the size you enter so there is a shadow gap between the frame and canvas. If you do not want any additional gap, you will need to deselect the 'Shadow Gap' option. Deselecting the 'Shadow Gap' will mean the floater frame is manufactured 2-4mm larger than the sizes entered, so your canvas just fits the frame.
You should also note the internal depth of the canvas floater frame which is detailed within the product description, and ensure this is suitable for the thickness of your canvas. It is perfectly normal for the thickness of your canvas to be slightly more or less than the internal depth of the frame.

I am ordering a picture frame for a stretched canvas

Our range of canvas picture frames are normal picture frame with deeper rebates, and are supplied without any glazing or backing. When measuring your canvas it is important to not presume that it will be square. Measure each outer edge of the stretched canvas, i.e. top, bottom, left and right, and use the larger of the two measurements(if there is a difference) when calculating the size you enter into our website. You should also consider any folded over canvas in the corners that will may also need to be allowed for in your measurements. We will manufacture the canvas picture frame so that a stretched canvas measuring the sizes entered will fit perfectly into the opening at the back of the frame with a small amount of movement.

I am ordering a canvas stretcher bar

A canvas stretcher bar assembly will be manufactured so the external size is within 0-2mm of the sizes entered. Stretching a canvas is considered a job that should only be carried out by someone with the experience and equipment to do so. Any such person should understand how to measure a canvas to calculate the size they need to order, taking into consideration any bleed or wrap around required.

What "External mount size" means on my order

Only shown for mount-only orders. Matches the external size of the mount board. If you are ordering frames separately, the external mount size should match the frame size. If you are ordering a mount to fit an existing frame, the external mount size should match the size of the glazing/backing in the current frame.

What image size "To Take" and "Exact" mean

"To Take" adds ~3mm overlap per side so your artwork doesn't fall through(default option). "Exact" cuts precisely to your entered size (advanced option).

Still not sure?

Get in touch before you order, or consult a local picture framer. Because of the many variables involved, we can't give detailed measuring advice by phone or email.
