A fabric yardage calculator helps sewers estimate how much fabric to buy before starting a project. Because yardage depends on project type, body size, fabric width, and pattern matching requirements, guessing often leads to buying too little or wasting money on excess. Enter your project details below to get an accurate yardage estimate with waste factor and cost.

Pro tip: Always pre-wash your fabric before cutting if you plan to wash the finished garment. Cotton can shrink 3-5% after the first wash, which could affect your measurements. Buy an extra quarter yard for pre-shrinkage if needed.
How to Use the Fabric Yardage Calculator
Buying the wrong amount of fabric is one of the most common frustrations in sewing. Too little means a trip back to the store — and the bolt may be sold out or from a different dye lot. Too much wastes money and fills your stash with scraps you may never use. Our fabric yardage calculator takes the guesswork out by accounting for project type, body size, fabric width, and pattern matching to deliver an accurate yardage estimate in seconds.
Step 1: Choose Your Project
Start by selecting a project preset — simple skirt, A-line dress, maxi dress, blouse, pants, jacket, quilt, or curtain panel. Each preset loads a standard yardage range calibrated for medium sizing at 44-45 inch fabric width. If your project does not match any preset, select "Custom" and enter the base yardage from your pattern instructions.
Step 2: Select Your Size
Choose from XS through XL. Smaller sizes generally require less fabric because pattern pieces are narrower and fit more efficiently across the fabric width. Larger sizes may require additional yardage — the calculator automatically adjusts the base estimate up or down based on size. For garments, this can make a difference of half a yard or more.
Step 3: Set Fabric Width
Fabric width is a critical factor. A 60-inch wide fabric lets you place pattern pieces side by side more efficiently than a 36-inch fabric, meaning you need fewer yards of length. Quilting cotton is typically 44-45 inches wide, apparel fabric ranges from 45-60 inches, and specialty fabrics like lace or silk can be as narrow as 36 inches. Always check the bolt before calculating.
Step 4: Account for Pattern Matching
If your fabric has a directional print, nap (like velvet or corduroy), or a large pattern repeat, you will need extra yardage. Directional fabrics add about 15% because all pieces must be cut in the same direction. For pattern repeats, enter the repeat length in inches — the calculator adds enough extra fabric to ensure you can match the pattern at every seam.
Step 5: Review Your Results
The results show four key numbers: base yardage (the minimum for your project and size), total with waste factor (adds 10-15% for squaring up, cutting errors, and fabric defects), yardage with pattern matching adjustment, and an optional cost estimate if you enter a price per yard. The final "With Pattern Match" number is the amount you should buy at the store. Round up to the nearest quarter yard when purchasing.
FAQ
Is this fabric yardage calculator free?
Yes, the fabric yardage calculator is completely free to use. There is no signup, no account, and no hidden fees. Use it as many times as you need for any sewing project.
Is my data safe and private?
Absolutely. All calculations run entirely in your browser using JavaScript. Nothing you enter is sent to any server or stored anywhere. You can even disconnect from the internet after loading the page and the calculator will continue to work.
How does fabric width affect how much yardage I need?
Wider fabric allows you to fit more pattern pieces across its width, which means you need fewer yards of length. A 60-inch wide fabric can require 20-40% less yardage than a 36-inch fabric for the same project. Always check the bolt width before purchasing, as quilting cottons are typically 44-45 inches while home decor fabrics are usually 54-60 inches.
What is a pattern repeat and why does it matter?
A pattern repeat is the distance before a printed or woven design starts over. When sewing with patterned fabric like stripes, plaids, or large florals, you need extra yardage to align the pattern at seams. The larger the repeat, the more extra fabric you need. A 12-inch repeat can add 10-25% more yardage to your project.
What is directional fabric (nap)?
Directional or napped fabric has a texture or print that runs in one direction, like velvet, corduroy, or one-way prints. All pattern pieces must be cut in the same direction, which means you cannot flip pieces to save fabric. This typically adds about 15% more yardage compared to non-directional fabric.
How much extra fabric should I buy for waste?
The calculator includes a 10-15% waste factor automatically. This accounts for squaring up fabric ends, cutting errors, and fabric that is not perfectly on-grain. For beginners or complex projects, consider adding an extra quarter yard on top of the calculated amount for peace of mind.
How accurate are the project presets?
The presets use standard yardage ranges based on common pattern sizes and are accurate for most standard patterns. However, every sewing pattern is different. If your pattern specifies a yardage amount, use the custom option and enter those dimensions instead. The presets are best used for planning and budgeting before you have a specific pattern.
Can I use this calculator for quilting projects?
Yes, the calculator includes a queen quilt preset that estimates 8-10 yards of primary fabric. For quilts with multiple fabrics, calculate each fabric separately based on how many blocks or sections use that fabric. Remember that quilting cotton is typically 44-45 inches wide, so select that width option.
