When searching for cushions to buy, you’ll soon find that there’s an endless range of dimensions to choose from. From extra-large floor cushions to long and thin draught excluders, small rectangular sofa cushions and more — such a large scope of cushion sizes can be tough to wrap your head around. When it comes to dressing your sofa or bed, however, there’s a limited range of sizes that tend to work the best. Here are the standard cushion sizes that you’re likely to come across in the UK, along with some tips on how to style them in your home.

Keep in mind, the following measurements are taken from cushion covers laid flat and unstuffed. Once filled, your cushion cover may compress and become a touch smaller. Measuring your sofa or bed will give you the best idea of which cushion sizes to go for, and how many cushions you’ll be able to fit in your arrangement.

60x60cm cushions

Some of the largest designs used to style beds and sofas, 60x60cm cushions are great for providing substantial back support and comfort. They tend to look best on larger-sized beds and sofas where smaller cushions can become lost in the space.

55x55cm cushions

If you like a large cushion but don’t want to overwhelm your sofa or bed, 55x55cm cushions offer a versatile middle ground. They bring significant comfort and visual impact, while creating an aesthetically-pleasing contrast with smaller cushion sizes.

45x45cm cushions

A match made in heaven with medium-sized sofas and beds, 45x45cm cushions are perfect for creating a rich and balanced arrangement when you’ve got less space to work with.

43x43cm cushions

Ideal for playing with height and dimension by pairing with slightly larger or smaller designs, 43x43cm cushions are incredibly versatile accessories. They can be used in a wide variety of cushion arrangements, while being compact enough to fit in smaller seating areas.

30x50cm cushions

Experimenting with shape is a great way to elevate any cushion and arrangement. Rectangular 30x50cm cushions create an interesting contrast with larger square designs, bringing a sense of depth and balance to your bed or sofa.

Whether you’ve got a cushion cover that needs the perfect pad, or an insert that you’re hoping will fit in one of our stunning covers — taking the correct measurements is crucial. There are countless cushion sizes that vary by only a centimetre or two, so using the correct measuring technique can be the difference between a perfectly-plush cushion and one which falls short. Here’s our method for accurately measuring cushion sizes, which can be used to find the precise dimensions of both covers and pads.

1. Lay it flat

Place your cushion cover or pad on a flat surface, making sure that it’s not compressed or misshapen in any way.

2. Measure the width

Grab a measuring tape and extend it across the widest section of your cushion cover or pad. Make sure that you’re measuring in as straight a line as possible.

3. Measure the length

Extend your measuring tape across the longest section of your cushion cover or pad, measuring from one edge’s seam to the other.

If you’ve got a round cushion cover or pad, simply find its diameter by measuring in a straight line through the centre. Following this method will give you precise dimensions, but taking multiple measurements is always best for ensuring the highest level of accuracy.

To find the perfect cushion cover size for your insert, lay the pad on a flat surface, then measure its length and width from seam to seam. Jot these figures down, and start searching for a cushion cover that lines up with the dimensions of your pad.

Here at furn. — we fill our cushion covers with pads that correspond exactly to the covers’ dimensions. This gives the cushion cover a snug and precise fit, preventing the edges from sagging and ensuring a comfortable finish.

If you’ve got your cushion cover sorted and just need to know what size cushion pad to fill it with, you’re in the right place.

First step, measure your cover. Simply lay your cushion cover on a flat surface, then measure along the edges to find its exact length and width. If it’s a round cushion cover, just measure the diameter (straight across the middle).


cushion covers + pad sizes: how to match them up.

Once you know the length and width of your cushion cover or pad, it’s time to select the perfectly-sized companion to go with it. Here’s a simple breakdown of the cushion cover and insert sizes that we pair together when filling our cushions.

While a helpful guide, it’s important to remember that these measurements aren’t the be-all and end-all. The right ratio of cushion cover to pad size depends on your desired fit. If you’d like a more plump-feeling cushion, simply choose a cushion insert that’s slightly larger than your cover. Similarly, if you’d prefer a more generously-cut cushion, go with a cushion cover that’s slightly larger than your insert.


how to fill your cushions like a pro.

Most of our cushions are available to buy just as a cushion cover, or pre-filled with a polyester or duck feather pad. Once you’ve chosen the right cushion filling for your needs, inserting it into your cushion cover is simple. Here’s how we fill our cushions for a perfectly-plump fit every time — a method which you can easily follow at home.

1. Lay your cushion cover on a clean, flat surface.

2. Fold your cushion pad in half lengthwise.

3. Place the pad inside your cushion cover, making sure that the top of the fold reaches a far corner of the cover.

4. Let the pad unfold to the opposite corner of your cover.

5. Rotate your cushion, ensuring each corner of the pad is tucked into a corner of the cover.

6. Grab the corners and shake to ensure that the cushion filling is distributed evenly.

7. Zip up your cushion, give it a plump, and voila! You’ve got a perfectly-filled cushion that’s ready to make a statement on your sofa or bed.
