Pillow Size Guide: UK Pillow Sizes and How to Choose the Right One

Choosing the right pillow size can make a big difference to how comfortable your bed feels. From standard UK pillow sizes to larger options for king and super king beds, the right choice depends on your bed size and how you sleep.

In this guide, we’ll break down common pillow sizes, how to choose the right one, and how to style cushions on your bed and sofa.

UK Pillow sizes explained

Standard pillows are the most common size in the UK and work well for most beds. Super king pillows are designed for larger beds, helping to fill the width and create a more balanced look.

How to choose the right pillow size

Choosing the right pillow size depends on your bed and how you sleep. The right fit will help your bed look balanced and feel more comfortable.

By bed size

Your mattress size is the best place to start.

• Single and double beds = Standard pillows (50 x 75cm) are usually the best fit

• King and super king beds = Super king pillows (50 x 90cm) help fill the space and create a more balanced look

By sleep style

How you sleep can also affect which pillow size works best.

• Restless sleepers: A larger pillow can offer more space to move during the night

• Minimal sleepers: Standard pillows are often enough for comfort and support

Most people use one or two pillows depending on comfort and support preferences.

By firmness

Pillow size is important, but firmness also plays a key role in comfort and support.

• Soft pillows: Best for front sleepers or those who prefer a lower profile

• Medium pillows: A balanced option suitable for most sleepers

• Firm pillows: Ideal for side sleepers who need extra neck support

By bedroom style

Your pillow choice can also affect how your bed looks.

• Standard pillows create a simple, clean look

• Larger pillows help fill space on bigger beds

• Mixing sizes can create a more styled finish

How many pillows should you have on a bed?

The number of pillows you use depends on your bed size and how you like your bed to look.

• Single bed - 1 to 2 pillows

• Double bed - 2 to 4 pillows

• King size bed - 2 to 4 pillows

• Super king bed - 2 to 6 pillows

You can keep it simple with just a couple of pillows or add more for a fuller, layered look

What’s the difference between pillows and cushions?

Pillows are designed for sleep and support, while cushions are mainly decorative.

• Pillows: Used for sleeping and supporting your head and neck

• Cushions: Used for styling and added comfort on beds or sofas

Both can be used together to create a comfortable and well-styled bed.

How to arrange cushions on your bed

Scatter cushions are an essential part of creating the perfect cosy bed set-up. However, with such a wide choice of different sizes and shapes, it can be tricky to know what will work best in your bedroom. So, let’s explore!

Keep it simple

For a clean, minimalist look, stick to a symmetrical layout and a smaller number of cushions.

• Use two to four cushions depending on bed size

• Place them evenly in front of your pillows

• Choose similar colours or tones for a cohesive finish

Create a layered look

For a fuller, more styled bed, layer cushions in different sizes.

• Start with larger cushions at the back

• Add medium cushions in front

• Finish with smaller cushions at the front

This creates depth and gives your bed a more relaxed, hotel-style feel.

Choose a colour palette

Keeping to a consistent colour palette helps your bed look more put together.

• Stick to two or three complementary shades

• Mix textures rather than too many colours

• Use your bedding as a base and build from there

You can also swap cushions seasonally, using lighter fabrics in summer and heavier textures in winter to change the look and feel of your bed.

Find the right balance

Adding cushions can enhance your bed, but too many can feel cluttered.

Start simple, then add more if you want a more layered look. The right balance will depend on your bed size and personal style.

How to measure your cushions

Getting the right cushion size starts with accurate measurements.

• Square or rectangular cushions - Measure the length and width from edge to edge

• Round cushions - Measure across the centre to find the diameter

• Cushion covers - Lay the cover flat and measure the width and height

Choosing the correct size helps cushions look fuller and sit neatly in their covers. For a fuller, more plump look, many people choose a cushion cover that is slightly smaller than the cushion pad.
