How Much Fabric Do I Need? A Practical Guide to Fabric Quantities
Share
The amount of fabric you need depends on its width, the pieces you’re cutting and how they fit together. Shrinkage, pattern matching and the direction of the cloth can all affect the final quantity.
A little planning before you order helps avoid waste—and a second order that may come from a different batch.
Start with your sewing pattern or project measurements
For garments, check the fabric requirements on your pattern. Choose the quantity for your size, view and fabric width, and read any notes about nap or directional prints.
Check whether the allowance includes lining, interfacing and other fabrics. These are often listed separately.
Without a pattern, make a list of every piece you need to cut. For cushions, curtains, upholstery or scenery, record:
- The number of pieces.
- Each piece’s cutting length and width.
- Any required grain or pattern direction.
- Whether pieces can be joined.
Use cutting measurements rather than finished measurements: include seams, hems, headings, overlaps and other construction allowances.
Check the usable fabric width
Fabric is usually sold by the metre along its length. The width is fixed, so one metre of narrow cloth gives you less cutting space than one metre of wide cloth.
Check the width on the product page before calculating your quantity. Allow for selvedges if they won’t be included in the finished piece, and for any width lost through pre-washing.
If your fabric is a different width from the one specified by your pattern, don’t simply adjust the quantity in proportion. Pattern pieces may fit together differently—or a large piece may no longer fit across the cloth.
Plan a cutting layout
Draw the usable fabric width to scale, then arrange your cutting pieces within it. Keep each piece in the correct grain direction.
For a sewing pattern, you can also lay the paper pieces out between two lines marking the usable width.
This shows how much length you need more accurately than adding up the area of the pieces. A layout may leave gaps that are too small or the wrong shape to use.
Example: fabric for two cushion covers
Suppose you’re making two simple cushion covers, each with a finished size of 45 × 45cm.
With a 1.5cm seam allowance on every edge, each front and back measures:
45cm + 3cm = 48cm square
You need four squares in total.
On cloth with a usable width of 140cm, two squares fit side by side. Two rows therefore use:
48cm × 2 = 96cm of fabric
That is the cutting requirement for plain cloth before shrinkage or any additional allowance. An envelope back, piping, pattern matching or a directional design would change the calculation.
Allow for fabric shrinkage
If the finished piece will be washed, check the fabric’s finish and test its shrinkage before deciding how much to buy.
Calculate the length needed before washing by dividing your required cutting length by the proportion that will remain.
For example, if your layout needs 2 metres and your test shows 5% length shrinkage:
2 ÷ 0.95 = 2.11 metres before washing
Check width shrinkage separately: it may change how many pieces fit across the cloth.
Our fabric shrinkage guide explains loom-state and pre-shrunk finishes, testing and allowances.
Allow for stripes, checks and pattern repeats
Patterned cloth often needs extra length so the design lines up across seams or neighbouring pieces.
Check the repeat along the length and across the width. Then plan where the pattern should sit—for example, centred on a cushion or aligned across curtain panels.
The extra quantity depends on the repeat and cutting layout. A large motif may need considerably more allowance than a narrow stripe, so a standard percentage won’t always be enough.
Keep directional fabrics facing the same way
Nap, pile, one-way prints and some surface finishes need all pieces cut in the same direction. Turning a piece to save cloth may change its appearance.
Check the fabric in good light before finalising your layout. If direction matters, use a one-way layout throughout.
What to check for different projects
| Project | Include in your calculation |
|---|---|
| Garments and toiles | Pattern requirements for the correct size and width, grain direction, alterations and any separate lining or interfacing. |
| Cushions | Fronts, backs, seams, closures, piping and pattern placement. |
| Curtains | Fullness, number of fabric widths, finished drop, headings, hems, pattern repeat and separate lining. |
| Upholstery | Every panel, including sides and concealed sections, plus fixing allowances, piping and matching. |
| Sets and props | Finished coverage, joins, hems, attachment points and any spare cloth needed for changes or repairs. |
For unfamiliar or complex upholstery, confirm the cutting plan with the person doing the work before ordering.
How much spare fabric should you allow?
Add spare cloth for a specific reason rather than automatically adding the same percentage to every project.
You might need enough for a test seam, dye trial, fitting adjustment, replacement panel or future repair. For a straightforward project with a checked layout, the allowance may be small. For a developing costume or set build, it may need to be larger.
Where colour consistency matters, ordering the full requirement together helps reduce the risk of differences between batches.
Metres, yards and roll lengths
Check the units before ordering:
1 yard = 0.9144 metres
1 metre = approximately 1.094 yards
Convert the quantity, then round up to the purchase increments available on the product page.
Wolfin supplies cloth by the metre and, for many fabrics, by the roll. Check the listed roll length rather than assuming every roll contains the same amount.
We cut orders as one continuous length up to 15 metres. If your project needs a longer unjoined piece, confirm the available supply format before ordering.
Before you place your order
Check your cutting layout against the actual cloth width, then include any shrinkage, matching and project-specific allowances. Confirm that you’ve counted every piece and any separate fabrics.
Order samples to assess colour, weave and handle before buying.
