How to Measure for Replacement Patio Cushions
When you measure for replacement patio cushions you can either measure the old cushions that you will be replacing or the furniture itself. Remember in all cases to use a proper measuring tape rather than try and struggle with an old ruler – that is bound to lead to mistakes.
Measuring from Existing Outdoor Patio Cushions
For patio chair cushions, measure the width and length of the back rest part of the cushion taking measurements from edge to edge (rather than seam to seam) for the width and from the top edge to the break or fold in the cushion (where the seat part of the cushion starts) for the length. This gives you the seat back measurement. Then take the length and width of the seat part of the cushion separately.
For a patio bench, chaise lounge or lounger cushion, measure the whole length and width from edge to edge.
For a seat pad cushion, measure the length and width edge to edge (or the diameter of a round cushion).
Finally measure the thickness of your cushion and note that measurement too. Thicknesses may not match if cushions have received uneven wear – just get a rough idea of a suitable thickness for your patio furniture cushions.
If your cushions have been well used, remember that they may have “spread out” a little and take this into account with all your measurements.
Measuring for Patio Cushions Using Your Outdoor Furniture

measuring for patio cushions
If you do not have the old patio cushions to measure, you can take measurements from your furniture itself. If existing cushions are well squashed out of shape this may also give more accurate measurements.
To measure for a patio chair cushion, measure across the seat of the chair – this will give you the width of the cushion. (If there are armrests in the way measure the width across the seat inside the armrests.) Then measure from the back of the chair where you would like the top edge of the cushion to finish, to the start of the seat (where the break or fold in the cushion would come) to give the back length. (Cushions may be the whole length of the back or stop a little short of it) Measure from the back of the seat (the fold area) to the front edge to give the seat depth.
To measure a garden bench or lounge chair you just need the width of the seat (take measurements as for the patio chair) and then the whole length of the chair.
To measure for a seat pad take the width and length of the seat (or the diameter in the case of a round seat).
To estimate the thickness of cushions for a patio chair, visualize how your cushion will look as various thicknesses. What would look too thin/too thick/just about right?
When looking at ready made cushions you are looking for the nearest match for your chairs. You should be able to find something not too different which will be suitable.
If there is nothing available however don’t despair, you can always try custom replacement patio cushions.

Where can I find piping to use on the patio cushion covers that I am making to cover my old cushions?
Hi Deborah
You might find piping for your patio cushions in the haberdashery department of large department stores or call a few shops which do normal upholstery and see if they have something suitable they could sell you.
If all else fails do a search online for piping for patio cushions or piping supplies for upholstery.
I hope you find what you are looking for because piping gives patio cushions the edge (literally!) over non-piped cushions.
I am trying to find replacement buttons for my outdoor cushions. It looks to be a 2 pc plastic button, that snaps together. I have tried to seperate the old one and they will not come appart. I orignially bought the coushion through a high end furniture store. No longer can afford that so I am going to make my own. These 2 pc buttons are about 2″ thick (meaning they expand about 2″). Please help anyone.
Hi AJ,
these buttons on your patio cushions sound like the type of covered buttons I used to make in sewing class but then they were small and made of metal You covered the outer part in fabric and then used the inner part to fix the fabric in place. I’m not sure what you mean by 2″ thick because that seems huge for a button. I think your best bet is to ask a local upholsterer about them as they are bound to know what these are and may be able to supply them too. Good luck with renovating your outdoor cushions. Perhaps you could let us know how you get on?

I am sorry, I think I mislead u. The whole unit is all plastic. and the male side snaps into the female side then it is a one piece thing that is extended out 2 inches. I wish I could get a clear picture of it and e-mail it to u.
Thanks, AJ.
AJ, Now I’m completely puzzled about how your patio cushions look
An upholsterer may still be able to help you. In any case, do you need to replace those plastic parts to make replacement cushions or could you remove the covers and use the inner parts of the cushions and recover them?
hi —– anyone know where i can find patio chair cushion covers ??? — i currently have cushions with a zipper back and would like to replace them
Hi Christine
you should be able to get patio chair cushion covers online if you do a search on Google. The problem will be trying to get an exact fit if you go for standard covers. If you choose custom covers on the other hand you might find it cheaper to get new cushions altogether. If you’re handy with a needle you can make your own covers but it’s beyond my skill level I have to admit as the special water and fade resistant patio cushion fabric is quite stiff and difficult to work with.

[...] When choosing a patio furniture replacement cushion make sure you measure your furniture first. You will find patio cushions comes come in many standard sizes but you have to get the right standard size so that the cushion can be secured to the chair with ties and is not slipping all over the place. If your patio furniture is not in a standard size then you can look for custom cushions which are available from a number of sites. They are a little more expensive but worth it to get a good fit.
