Kalkulator Pengukuran Benang dan Kain

Stop guessing how much fabric to buy. This calculator turns your garment plan and body measurements into a precise yardage estimate that accounts for fabric width, hems, sleeves, pattern matching, and a buffer for shrinkage and mistakes. Use it before every trip to the fabric store so you walk out with enough — but not too much.

Cara Penggunaan

Pick the garment you are making: skirt, shirt, dress, pants, or quilt blocks.
Choose your unit system — imperial (inches and yards) or metric (centimeters and meters).
Select the fabric width from the bolt label (45, 54, or 60 inches; 115, 137, or 150 cm).
Enter the relevant body measurements: bust, waist, hip, garment length, and sleeve length as needed.
For quilts, enter the finished block size, number of blocks, and seam allowance.
If your fabric has a vertical pattern repeat (plaid, stripe, large print), enter the repeat length so the calculator can add one repeat per panel for matching.
Adjust the buffer slider — 10% is a safe default that covers shrinkage, cutting mistakes, and small fabric flaws.
Read off the recommended fabric to buy in both yards and meters, and check the breakdown table to see exactly how the number was built up.

Fitur

Five garment types – A-line skirt, shirt or blouse, shift dress, trousers, and quilt blocks each use their own lay-out logic.
Imperial and metric – Enter measurements in inches or centimeters; the result always shows both yards and meters.
Fabric width aware – Different bolt widths change how many lay lengths you need, which can cut required yardage in half on wider fabric.
Pattern-repeat allowance – Adds one repeat per panel so plaids and large prints can be matched at the seams.
Adjustable buffer – Slide from 0% to 25% to cushion for shrinkage, cutting errors, or extra confidence.
Transparent breakdown – See lay length, panel count, extras, pattern add, and buffer line-by-line so you can sanity-check the math.
Rounded to quarters – Final yardage rounds up to the nearest 0.25 yd or 0.25 m, matching how fabric is sold at the counter.
Hasil instan – Recalculates as you change garment type, width, or measurements; no submit button needed.

 Tanya Jawab Umum

Why does fabric width change how much I need to buy?

Fabric comes off the bolt as a long strip of fixed width. If your garment piece is wider than the usable width (bolt width minus the selvage edges), you have to lay it down twice end-to-end, doubling the length you need. A 60-inch bolt can often fit front and back side-by-side in one length, while a 45-inch bolt forces two lengths — sometimes nearly twice the yardage for the same garment.
What is a selvage and why does the calculator subtract from the width?

The selvage is the tightly woven edge running down both long sides of the fabric. It is usually denser, slightly discolored, and not suitable for use in the finished garment because it shrinks differently from the rest of the fabric. The calculator subtracts a 2-inch allowance for both selvages combined to give a realistic usable width.
What does pattern repeat mean and when do I need to add for it?

Pattern repeat is the vertical distance after which a print, plaid, or stripe starts over. To make the design line up at seams (especially center front, side seams, and shoulder seams), each cut piece may need to start at the same point in the repeat — which can waste up to one full repeat per panel. Add the repeat length to the calculator only if you intend to match the pattern; solids and small all-over prints do not need this.
Why is a buffer for shrinkage and mistakes recommended?

Natural-fiber fabrics like cotton, linen, and wool can shrink 3 to 10 percent on the first wash. On top of that, a cutting error, off-grain bolt, or visible flaw in the fabric can force you to recut a piece. A 10 percent buffer absorbs both risks. For pre-washed fabric or simple shapes you can drop closer to 5 percent; for a beginner project with matching, 15 to 20 percent is safer.
How do commercial pattern envelopes calculate their yardage chart?

Pattern companies test-lay every size against standard fabric widths and record the minimum yardage that fits without piecing. Their charts vary by size, sleeve length, and fabric width for that reason. This calculator uses the same lay-length and panel-count logic in a simplified form, with conservative ease and hem allowances built in — close enough for shopping but not a substitute for following the actual pattern envelope when you have one.
