How to Measure Replacement Garden Cushions Correctly (Step-by-Step Guide)

If you’re looking for replacement garden cushions, getting the measurements right is the most important step. Even a few centimetres can make the difference between a perfect fit and cushions that look untidy or slide around every time you sit down.

In this guide, we’ll show you exactly how to measure your existing cushions or outdoor furniture to ensure your new cushions fit perfectly.

Why Accurate Measurements Matter

Garden furniture comes in hundreds of different shapes and sizes. Even furniture that looks identical can often have slightly different dimensions.

Correct measurements help you:

  • Achieve a neat, professional look
  • Improve comfort and support
  • Prevent cushions from moving around
  • Avoid costly mistakes and returns
  • Get the most from custom-made cushions

What You’ll Need

Before you start measuring, grab:

  • A tape measure
  • A notebook or phone for notes
  • A camera (optional but helpful)

For best results, use a flexible tape measure rather than a rigid ruler.

Measuring Seat Cushions

For seat cushions, you need three measurements:

Width

Measure from one side of the seat to the other.

📏 Example: 120 cm

Depth

Measure from the front edge of the seat to the back.

📏 Example: 60 cm

Thickness

Measure the height of the cushion from top to bottom.

📏 Example: 10 cm or 15 cm

Example size:
120 × 60 × 10 cm

Measuring Back Cushions

Back cushions are measured slightly differently.

Width

Measure across the cushion from side to side.

Height

Measure from the bottom to the top.

Thickness

Measure the depth of the cushion.

Example size:
60 × 40 × 10 cm

Measuring Rattan Furniture Cushions

If your old cushions are missing or worn out, measure the furniture itself.

For rattan furniture:

  • Measure the internal seating area
  • Measure between the arms
  • Measure the usable depth
  • Check if corners are rounded

Many rattan furniture sets have slight variations, even within the same collection.

Measuring Pallet Sofa Cushions

Pallet furniture is usually made from standard Euro pallets.

Common sizes include:

Cushion TypeTypical Size
Seat Cushion120 × 80 cm
Seat Cushion120 × 60 cm
Back Cushion120 × 40 cm
Back Cushion60 × 40 cm

Always measure your pallet seating before ordering, as DIY pallet furniture often varies.

Measuring Corner Sofa Cushions

For corner units, measure each section separately.

Record:

  • Left section
  • Corner section
  • Right section

Do not assume both sides are identical.

A simple sketch with dimensions can help avoid confusion when ordering custom cushions.

Measuring Bench Cushions

For bench cushions, measure:

  • Length
  • Depth
  • Desired thickness

Popular bench cushion depths are:

  • 30 cm
  • 35 cm
  • 40 cm
  • 45 cm

For window seats, measure the recess carefully and check whether the corners are square or rounded.

Should You Measure Existing Cushions or Furniture?

If your current cushions fit perfectly, measure the cushions.

If your cushions are old, sagging, misshapen or missing, measure the furniture instead.

Furniture measurements are usually the more reliable option for replacement cushions.

Common Measuring Mistakes

Measuring Curved Cushions Incorrectly

Always measure the widest points.

Forgetting the Thickness

Many customers remember length and width but forget thickness.

A 10 cm cushion feels very different from a 15 cm cushion.

Measuring from the Wrong Position

Measure the actual seating area, not the overall furniture frame.

Guessing

Never estimate measurements.

Even small errors can affect the final fit.
