Understanding picture frame sizes

We've created this guide to help you understand how sizes work in the framing world, and to clearly explain the options at your disposal. Framing online can at first be a little bit tricky to get your head around, especially if you've never tried it before. We get many questions relating to size of artwork/size of frames for example: 'I have X size picture, what frame size do I need?' . The answer to that question depends on one or two things, as we'll explain below.

Do you want a border (mount) around your picture?

This obviously depends on your personal taste, the type of artwork itself and probably the area where it will be displayed. A picture mount is a type of purpose-made card that you often see in framed artwork and photography.  As you can see below, frames with and without a mount contrast each other strongly: 

picture frame sizes with without mount split	In the first image, we can see the white mount border surrounding the picture. This provides more 'breathing space' around the image, and sets the image away from the frame. Your mount will arrive inside the frame, and will have a cut out/aperture inside to fit your picture size - the cut out that we will send to you will be ever so slightly smaller (3mm) on each side (left, right, top and bottom) to make it easier for you to align the image with the cut out.

In the second image, the picture is framed with no mount border i.e. the image has gone directly into the frame. Generally this is a more popular choice when framing larger posters in contrast with smaller artwork, but again this is completely subjective and down to your personal preference. 


How do mounts affect the size of the frame?

If (for example) you have two prints both of which are the same size, and you would like one of them mounted inside a frame, and one of them straight into a frame with no mount then the overall size of the frames will be different.

The frame with your print and the mount around it will be larger in size overall. This is because you must consider the size of the print + the mount border all away around your print + the frame itself. This would provide a larger external (or wall space) measurement than simply 'your print + the width of the frame around your print'. 


How does this affect the way I choose frames?

We offer both frames that are available in ready made sizes as well as the ability to create your own custom size frames and mounts, so which is the best option? Let's take a look at the following scenarios:


'I don't want a mount - I want the image to go straight into a frame'

In this scenario you'll need to find out whether you have a standard sized picture or not. If your picture is a standard size, you can buy a ready made frame to fit your picture perfectly.

If your picture is an uncommon or non-standard size then don't worry, all you have to do is visit our custom frames page, type in the size of your picture and ensure you select 'no mount, thanks'. Our custom frames are expertly manufactured in wood and available in a huge range of colours and styles.


'Yes, I'd like to have a mount around my picture in the frame'

The easiest way to frame your artwork with a mount included is to head over to our dedicated page. You now have the ability to play around with the different frames styles and colours on offer, as well as the different colours of mounts available. The framing tool also allows you to to adjust the size of the borders of the mount around your picture, allowing you to create some incredibly striking effects.

Make sure you keep an eye on the external size of the custom frame (wall space - viewable in the summary section at the bottom of the custom frames page) as the bigger border sizes around the picture you choose, the larger the outside of the frame will be. 


'I would like a mount around my picture, but in a Nielsen frame'

This is essentially the 'third option' but still a very popular one with our customers. It can also be a little bit tricky to get your head around for the first time. 

First, head over to our dedicated page for creating custom mounts to fit Nielsen ready made frames. Then in Step 1 'About your picture' you'll need to input the size of your picture (you can do this in either mm / cm or inches).

After choosing the colour and style of your mount, you will then reach Step 3 'Which Nielsen frame would you like?'. Here, our website has automatically set the outside dimension (i.e. frame size) of your mount to be the same as a ready made Nielsen frame size (these sizes refer to the picture size the frames are made to accommodate). It then provides a list of all the ready made Nielsen frames that are available for you to fit you current mount into. Remember: the external size of the mount will equate to the standard size Nielsen frame your custom mount will go into. 

As you can see, if you increase the frame size, the borders around your picture will increase and vice versa. You can then choose a frame of your liking from the available list, and add both the frame and mount (and backing mount if you wish) to your basket all in one go.
