Updated: May 26, 2026

Typical Sofa Cushion Sizes

Standard sofa seat cushions (US and UK):

Sofa Type	Cushion Width	Cushion Length	Thickness	Count
2-seater sofa	24”–26”	22”–24”	4”–5”	2
3-seater sofa	24”–26”	22”–24”	4”–5”	3
Large sectional	24”–28”	24”–26”	5”–6”	3–5

Actual dimensions vary widely by manufacturer. Always measure your foam inserts before buying fabric.

Fabric Yardage per Cushion

Using 54” fabric, ½” seam allowance, box cushion construction:

Seat Cushions (common sizes)

Size	Thickness	Yards (no piping)	Yards (with piping)
22”×22”×4”	4”	1.2	1.4
24”×24”×4”	4”	1.3	1.5
24”×24”×5”	5”	1.4	1.6
26”×24”×5”	5”	1.5	1.7
28”×26”×5”	5”	1.7	1.9

Full Sofa Set: Total Fabric Needed

The calculator below covers just seat cushions. Many sofas also have back cushions (typically thinner and shorter). Budget back cushions separately.

3-Seater Sofa Seat Cushions Only

3 cushions, 24”×24”×4”, 54” fabric:

Configuration	Total Yards
No piping, no lining	3.2
With piping	3.7
With piping + 10% safety	4.1

Order: 4–4.5 yards for a standard 3-seater sofa seat cushion set.

3-Seater Sofa: Seat + Back Cushions

Typical back cushions: 24”×12”×4” (shorter height, same width, thinner)

3 seat cushions (24”×24”×4”) + 3 back cushions (24”×12”×4”):

	Yards
Seat cushions	3.2
Back cushions	2.0
Total (no piping)	5.2
Total (with piping on all)	6.0

Order: 6–7 yards for a full 3-seater sofa seat + back cushion set.

3-Seater + Armchair Set (Matching Fabric)

Piece	Qty	Size	Yards Each	Total
Sofa seat cushions	3	24”×24”×4”	1.3	3.9
Sofa back cushions	3	24”×12”×4”	0.8	2.4
Chair seat cushion	1	22”×22”×4”	1.2	1.2
Chair back cushion	1	22”×10”×4”	0.7	0.7
Total (no piping)				8.2 yards
Add 10% safety				~9 yards

Does Piping Use a Lot of Extra Fabric?

No. Piping adds only ½–¾ yard to a typical 3-cushion sofa project.

Why so little? Piping strips are only 1.5” wide. A single 1.5” × 54” strip yields 54” of piping length. A 24”×24”×4” box cushion needs about 204” of piping — only 4 strips = 6” of fabric = under ¼ yard.

For 3 cushions: about ¾ yard of piping fabric total. For full piping construction and cutting instructions, see How to Add Piping to Cushions.

Pattern Repeat: How Much Extra Fabric?

If your chosen fabric has a pattern repeat (a repeating design motif), each cushion panel must be cut starting at the same point in the repeat so patterns align across cushions.

Extra fabric needed = 1 pattern repeat per cushion width (per row across the fabric):

Extra per fabric width row = 1 pattern repeat
Rows for 3 cushions on 54" fabric:
  Panels: 3 rows (3 pairs of panels)
  Boxing: additional rows for boxing strips
Extra = 3 rows × repeat length

For an 8” repeat: 3 rows × 8” = 24” = ⅔ yard extra. Order the next full yard (add 1 yard above your base calculation when using patterned fabric). The complete pattern repeat formula is in Cushion Fabric Formulas.

Cost Comparison: New Cushion Covers vs New Cushions

Recovering existing foam inserts vs buying new pre-made cushions:

Option	3-Cushion Sofa	Quality
Pre-made replacement cushions (budget)	$60–$120	Low — usually polyester fill
Pre-made replacement cushions (quality)	$150–$300	Better — foam core
DIY covers from $15/yard fabric	$60–$90 fabric + thread	Custom — exact fit, quality fabric
Professional re-upholstery	$300–$600+	Highest

DIY is cost-competitive with mid-range pre-made cushions and allows custom fabric selection and sizing.
