The 3-Colour, 3-Pattern Rule: How to Mix Cushion Patterns Like a Pro
A few well chosen cushions can turn a plain sofa into the focal point of a room. Yet mixing cushion patterns is where many people freeze. Does this stripe go with that floral? Is it too busy? The fear of getting it wrong often ends with a row of safe, plain cushions.
There is a simple formula designers use again and again: the 3-Colour, 3-Pattern Rule. This guide breaks it into clear steps, with an example you can copy.
Part 1: Build a 3-Colour Palette
Before you think about patterns, settle on a colour story. A tight palette is what stops a pattern mix from tipping into chaos. Every cushion you choose should draw from it.
- Main colour (about 60%). Your dominant shade, usually taken from the biggest thing in the room: the sofa, the rug, the curtains or a large piece of art.
- Secondary colour (about 30%). A shade that complements the main colour and appears often, such as navy with blush pink.
- Accent colour (about 10%). Your pop of colour. A brighter or bolder shade used sparingly, for example mustard, coral or a rich green.
Example: a grey sofa with teal as the secondary colour and a pop of mustard.
Part 2: Choose Three Patterns at Three Scales
The type of pattern matters less than its scale. For the rule to work you need a large, a medium and a small scale design.
Pattern 1: The lead pattern (large scale)
The star of the arrangement and usually the first cushion you choose. It should contain all three colours of your palette. Good choices are a bold floral, a large abstract or a big botanical print. Start with our floral cushion covers or abstract cushion covers.
Pattern 2: The secondary pattern (medium scale)
Roughly half the scale of the lead pattern, sharing one or two of its colours. If the lead is soft and organic, choose something more structured, such as a stripe, a check or a simple geometric. Our decorative cushion covers include plenty of mid scale designs.
Pattern 3: The supporting pattern (small scale or plain)
The quietest cushion in the group: a small repeat, a subtle texture or a solid colour. Its job is to give the eye a resting place. This is often where your accent colour comes in.
Why Scale Is the Secret
Think of your cushions as a conversation. If all three patterns are large and bold, everyone is shouting. If all three are tiny, everyone is whispering and nothing stands out. A large lead, a medium supporting pattern and a small or plain cushion give you different voices that work together.
Putting It Together: A Step by Step Example
- Choose the palette. Navy (main), white (secondary) and coral (accent) for a navy sofa.
- Find the lead. A large scale floral cushion in navy, white and coral.
- Add the secondary. A navy and white striped or geometric cushion at a smaller scale.
- Add the supporting cushion. A small pattern or plain cushion in coral.
- Arrange. Larger cushions in the corners, the medium pattern in front of them, and the smallest or a rectangular lumbar cushion in the centre.
Choosing Sizes That Layer Well
Varying cushion size helps as much as varying pattern. Our square cushion covers come in ten sizes from 30 x 30 cm (12 inches) to 70 x 70 cm (28 inches), and rectangular covers suit the front of the arrangement.
| Position | Suggested size |
|---|---|
| Back corners of a three seater | 50 x 50 cm or 55 x 55 cm (20 or 22 inches) |
| Middle layer | 45 x 45 cm (18 inches) |
| Front or centre | A rectangular lumbar, such as 30 x 50 cm |
| Large corner sofa or bed | 60 x 60 cm up to 70 x 70 cm at the back |
Many of our designs are printed on both sides, which is handy on beds and window seats where both faces show; others have the print on the front and a plain back. The size option on each product page shows which it is. Covers are sold without the inner pad. For a full size chart, see our cushion size guide.

Frequently Asked Questions
Do I have to use exactly three patterns?
No, it is a starting point rather than a law. You can simplify to two patterns and a plain cushion, or for a fuller look use five: one large, two medium and two small or plain.
How many cushions should go on a sofa?
Odd numbers tend to look more relaxed. Three or five suit a three seater, three suits a two seater, and a large corner sofa can take five or seven.
How does the rule work if my sofa is already patterned?
Treat the sofa as your lead pattern. Choose one medium scale pattern that picks up its colours, and add plain cushions for the rest.
Can I use more than three colours?
Yes, especially in a bohemian or maximalist scheme. Keep one or two colours as the base, then add small touches of others as accents.
What sizes work best together?
Mix sizes as well as patterns. For example, 50 x 50 cm or 55 x 55 cm at the back, 45 x 45 cm in the middle and a rectangular lumbar at the front.
Should the inner pad be bigger than the cover?
A pad slightly larger than the cover, often by about 5 cm, gives a fuller, plumper look. For example, a 50 x 50 cm pad in a 45 x 45 cm cover. Our covers are sold without pads.
What is the difference between single sided and double sided covers?
Double sided covers have the print on both faces, which is useful when both sides can be seen or when you like to flip them. Single sided covers have the print on the front and a plain back. Each of our designs comes in one of the two; the size option on the product page shows which.
Does the rule work on a bed?
Yes. Take your palette from the duvet cover or headboard, place the sleeping pillows at the back, then larger square cushions, then the patterned cushions in front.
Where does a rectangular cushion fit in?
At the front or in the centre. A rectangular lumbar breaks up a row of squares and is a good place for your accent colour.
How do I care for printed cushion covers?
Wash them inside out on a cool cycle, maximum 30°C, and tumble dry on low or dry flat. See our care guide for details.
