Before you go fabric shopping, it's always good to know how much fabric you will need for your project.
And if you've fallen in love with a fabric without a project in mind, it's good to know a few common fabric requirements for the projects you like to sew.
At Maaidesign, we want to help you order your fabric more confidently - not too much, not too little!
If we're being honest, there's no magic answer. But there are ways to work it out with a lot more accuracy.
Start with your pattern
Your pattern's fabric requirements should always be your first stop.
How much fabric you need depends on:
- Your size, including your height
- The style and finished length of the garment
- Sleeve length
- Whether your fabric has a nap or directional print
- Whether pattern matching is required
- The width of the fabric you're buying
-
Any alterations you plan to make
- The possible shrinkage of the fabric - always prewash it!
Design details change how much you need
A long-sleeve version of a pattern generally requires more fabric than the same garment with short sleeves. This is because longer sleeves may no longer fit neatly alongside the bodice pieces when you're planning your cutting layout.
For example:
Short Sleeve:
Long Sleeve:
Other details that can increase fabric requirements include:
- Full or gathered skirts
- Wide-leg trousers
- Large collars
- Yokes
- Pockets
- Ruffles and frills
- Pleats and gathers
- Extra-long hems
- Pattern matching
This is why a general fabric calculator can only ever give you an estimate. Your sewing pattern is the most accurate guide.
Cut direction matters too
How your pattern pieces need to be placed on the fabric can have a big impact on how much fabric you need.
Bias-cut garments
A bias-cut dress or skirt can use considerably more fabric than the same silhouette cut on the straight grain. Because the pattern pieces are positioned diagonally across the fabric, there can be more fabric waste at the edges.
How to read your pattern requirements
Most sewing patterns list fabric requirements in a table showing different fabric widths (usually around 140–150cm for dressmaking fabrics) across different sizes.
Find your pattern size, match it to your fabric width, and check whether the pattern lists separate requirements for nap or directional prints.
If your fabric width doesn't exactly match what's listed, don't automatically use the closest column. If there's a significant difference, it's worth checking the pattern layout or allowing some extra fabric.
Don't forget to check the fabric width
This is particularly important when buying fabric online.
Not all dressmaking fabrics are the same width. Some fabrics are 155cm wide, which can make a surprisingly big difference to how much fabric you need.
A pattern that calls for 2.5m of 140cm-wide fabric may require less fabric if you're using a much wider fabric, depending on how the pattern pieces are arranged.
The floor method
Still not sure? Try this simple method.
Lay your pattern pieces out on the floor or a large table, mark your fabric width with masking tape, and arrange your pattern pieces as efficiently as possible. You pattern often provides a suggested lay plan for all pattern pieces.
Then measure the total length your pieces take up.
Our in-house pattern maker swears by her tiled floor for this. Five minutes and a roll of masking tape can save a lot of guesswork.
Just make sure you follow the grainlines and any cutting instructions when arranging your pieces.
Use your previous makes
If you've sewn a similar style before, that pattern is one of your best references.
Get into the habit of noting on your pattern envelope:
- How much fabric you used
- The fabric width
- The size you made
- Whether it had a nap or directional print
- Any alterations you made
Over time, this becomes a personal reference that's specific to your body and your sewing habits.
A few final tips for buying fabric online
Check the fabric width.
Don't assume every dressmaking fabric is 140cm or 150cm wide. Some fabrics are considerably wider and that can change how much you need.
Allow extra for directional prints.
If your fabric has a one-way design, nap or prominent pattern repeat, you may need additional fabric for the cutting layout and pattern matching.
Consider your height.
Pattern fabric requirements are generally based on the measurements used by the pattern designer. If you're significantly taller than the pattern's height, you may need extra fabric, particularly for dresses, skirts, trousers and long sleeves.
Think about alterations.
Adding length, a full bust adjustment, a fuller skirt or wider trousers can all change your fabric requirements.
When in doubt, check before you cut.
It's much easier to order another half metre of fabric before you start sewing than it is to discover you've run out halfway through your project.
Still not sure how much fabric you need?
That's what we're here for.

We'd much rather help you work it out than have you discover you've run out halfway through cutting.
Frequently Asked Questions
How much fabric do I need to make a dress?
The amount of fabric needed for a dress depends on the pattern, your size and height, the fabric width, dress length, sleeve length and whether the fabric has a nap or directional print. Always check the pattern's fabric requirements before purchasing.
Does fabric width affect how much fabric I need?
Yes. A wider fabric can sometimes require less fabric length because pattern pieces can be arranged more efficiently. Always compare the fabric width with the width specified in your sewing pattern.
Should I buy extra fabric?
If you're making alterations, working with a directional print or nap, matching stripes or checks, or using an unusual fabric width, allowing some extra fabric can be a good idea.
