Standard Cushion Sizes Australia: A Complete Guide
Choosing the right cushion size can completely change how a sofa or bed looks. Too small and cushions can feel lost; too large and they can overwhelm the space.
This guide covers the standard cushion sizes in Australia, how to choose the right size for your sofa or bed, and how to layer different sizes for a more considered look.
Standard Cushion Sizes in Australia
| Size | Shape | Best For |
|---|---|---|
| 40 × 40 cm | Square | Armchairs, accent layering |
| 45 × 45 cm | Square | Standard sofas, single beds |
| 50 × 50 cm | Square | Sofas, beds, general use |
| 55 × 55 cm | Square | Sofas, queen & king beds — generous, luxurious feel |
| 60 × 60 cm | Square | Large sofas, floor cushions |
| 30 × 50 cm | Rectangular | Lumbar support, layering |
| 55 × 35 cm | Rectangular | Lumbar layering in front of larger square cushions |
| 40 × 60 cm | Rectangular | Large sofas, end of bed |
At 55 × 55 cm, Agasti cushions sit between the standard 50cm and 60cm sizes. This is the sweet spot — big enough to feel genuinely luxurious on a sofa or bed, without tipping into oversized floor-cushion territory.
What Cushion Size Should I Choose?
We offer two sizes designed to work together:
- 55 × 55 cm — our core size. Works on two, three and four-seat sofas, queen and king beds, and armchairs. The larger format gives cushions a weightier, more considered presence than a standard 45 or 50cm.
- 55 × 35 cm — a rectangular lumbar cushion. Layer one in front of your 55 × 55 cm cushions for a styled, considered look.
How Many Cushions for Your Sofa?
| Sofa Size | Cushions | Suggested Layout |
|---|---|---|
| 2-seater | 2 – 4 | 2 × 55cm squares, or 2 squares + 1 lumbar centred |
| 3-seater | 4 – 6 | 3 × 55cm squares at back + 2 lumbar in front |
| 4-seater / L-shape | 6 – 10 | Mix sizes and prints across both sections |
| Armchair | 1 – 2 | 1 × 55cm square, or 1 square + 1 lumbar |
Cushions on a Bed
| Bed Size | Cushions | Suggested Layout |
|---|---|---|
| Single | 1 – 2 | 1 × 55cm square centred, or 2 side by side |
| Double | 2 – 3 | 2 × 55cm squares + 1 lumbar in front |
| Queen | 3 – 5 | 2 × 55cm squares + 1 lumbar, or 3 squares across |
| King | 4 – 6 | 4 × 55cm squares in pairs + 2 lumbar in front |
Mixing Prints and Colours
Agasti cushions are designed to layer. A few principles that always work:
- Odd numbers look more natural. Three cushions on a sofa almost always looks better than two or four.
- Vary the texture, keep the palette. Mix our embroidered and block-printed covers — the craft is different but the colour story ties them together.
- Let one print lead. Pick a bolder print as the hero and use a quieter companion print behind or in front of it.
What Size Cushion Insert Do I Need?
Choosing the right cushion insert makes a big difference to the finished shape.
- For a softer, tailored look: choose an insert the same size as your cushion cover.
- For a fuller, plumper look: choose an insert 2–5 cm larger than the cover.
- Avoid an insert smaller than the cover: it can leave the cushion looking flat and unsupported.
Agasti cushion covers are available with or without an insert, so you can choose the finish that works for you.
