What size cushion to choose?

The ideal size of a cushion depends on the support (sofa, bed, armchair), the desired effect and the proportions of your space.
For a standard sofa, the most versatile sizes are 40x40 cm, 45x45 cm and 50x50 cm.
A 30x50 cm rectangular cushion is perfect as a complement.
The objective: to create volume without visually overloading the seat.

 

 

 

Why is the size of the cushion important?

A cushion is not just a decorative accessory.

It influences:

1. Comfort (lumbar support, headrest, relaxation)

2. Visual balance from the sofa or bed

3. The perception of volumes in the room

A cushion that is too small seems wasted.
A cushion that is too large crushes the seat.

The right size creates natural harmony.

Here are the standard formats used in interior decoration:

What size cushion for a bed?

The bed allows for more generous formats.

Bed 160–180 cm

• 2 cushions 60x60 cm

How to choose the ideal size? 

1. Measure the width of the support
2. Divide by 3 or 4 to obtain a consistent size
3. Check the seat depth
4. Test the proportion (the cushion should not exceed 2/3 of the height of the backrest)

 

Practical advice from experts

✔ For a high-end look, use fillings slightly larger than the cover (e.g. cover 45x45 cm + interior 50x50 cm).
✔ Multiply textures rather than sizes.
✔ Limit yourself to 2 or 3 formats maximum.
✔ Respect chromatic consistency.

 

 

 

 

Mistakes to avoid

1. Mixing too many different sizes
2. Choose only small cushions on a large sofa
3. Neglecting seat depth
4. Forget the comfort function in favor of the decorative

 

What size cushion for an armchair?

• 40x40 cm for a compact armchair

• 45x45 cm for a wide armchair

Avoid large size cushions which unbalance the silhouette.
