How to Measure a Loveseat for Custom Cushions

Loveseat cushions come as a two-piece set — a separate seat pad and back pad. Just like a sofa, the back pad rests on top of the seat pad, so the back height requires a calculation. Provide the full width of the frame — do not divide by two. You need six measurements across both parts.

Part A — Loveseat seat

Step 1 — Start here

Choose the seat cushion thickness

Select a thickness between 2 and 5 inches. Write this number down — you will need it in Step 6 to calculate the correct back cushion height.

Step 2

Measure the overall seat width

Measure the full width of the loveseat's seating area from one arm to the other. Provide the total — do not divide by two. We will handle the split based on your configuration.

Measure the frame, not your old cushions

Foam compresses and fabric stretches over time. Old cushions will give you inaccurate dimensions. Always measure the bare wood or metal frame directly.

Step 3

Measure the seat depth

Measure from the front edge of the seat frame to the back rail. If the frame has a front lip or rail, measure to the inside edge.

Part B — Loveseat back

Step 4

Choose the back cushion thickness

Select a thickness between 2 and 5 inches. Back cushions are often ordered 1 inch thinner than the seat for a more comfortable, natural posture.

Step 5

Measure the overall back width

Measure the full width of the back frame from side to side. This is usually the same as the seat width, but measure independently to confirm. Provide the total — we will divide it to match your seat configuration.

Step 6 — Calculation required

Calculate the back cushion height

The back pads rest on top of the seat pads, so they start higher than the bottom of the back frame. If you order the full frame height, the back cushions will sit too high and push the seat pads forward. Subtract the seat thickness from the total frame height.

Back height (order) = Total frame height − Seat cushion thickness

Worked example

Your loveseat back frame measures 28" tall. You chose a 4" thick seat pad in Step 1.

28" − 4" = Order 24" back cushion height.

Measuring tips

The book method

Unsure about thickness? Stack books on the seat frame until the height feels comfortable. Measure the stack to find your ideal thickness before committing.

Use a rigid tape measure

A steel retractable tape gives straight, consistent readings across wide loveseat spans. Avoid soft tailor's tape — it sags and causes errors.

Round to the nearest ½"

We produce cushions in ½" increments. Round each measurement to the nearest half-inch before entering dimensions at checkout.

Write Step 1 down first

The seat thickness from Step 1 is used again in Step 6. Note it before measuring the frame so you have it ready for the back height calculation.
