This pleated skirt calculator helps measure the precise amount of fabric needed to create a pleated skirt with specific dimensions and pleat styles.
By inputting variables such as waist measurement, desired skirt length, and pleat depth, the calculator provides accurate fabric requirements and pleat quantities.
When you’re crafting a midi-length pleated skirt with a 28-inch waist and 1-inch deep knife pleats, the calculator suggest using 2.5 yards of fabric and creating 56 pleats for an evenly distributed, full appearance.

Pleated Skirt Formula
The formula is:
Total fabric width = (Waist measurement × Fullness factor) + (Number of pleats × Pleat depth × 2)The pleated skirt formula considers three main factors:
- Waist measurement
- Desired fullness
- Pleat depth
Let’s break this down with an example:
- Waist measurement: 30 inches
- Desired fullness: 2.5 (moderate fullness)
- Pleat depth: 1 inch
- Number of pleats: 20
Plugging these values into our formula:
Total fabric width = (30 × 2.5) + (20 × 1 × 2)
= 75 + 40
= 115 inchesThis calculation indicates you’ll need approximately 115 inches (or 3.2 yards) of fabric for your pleated skirt.
How to Calculate Pleats for Skirts?
Measure your waist
Decide on the pleat depth
Choose a fullness factor (typically 2-3 for moderate fullness, 3-4 for high fullness)
Calculate the total fabric width using the formula above
Determine the number of pleats by dividing the excess fabric by twice the pleat depth
- Waist: 28 inches
- Pleat depth: 1.5 inches
- Fullness factor: 2.5
- Total fabric width: (28 × 2.5) + (X × 1.5 × 2) = 70 + 3X
- Solving for X (number of pleats): 3X = 70 – 28 = 42
- X ≈ 14 pleats
How Many Yards for a Pleated Skirt?
- Calculate total fabric width using the pleated skirt formula
- Add seam allowances and hem
- Divide by fabric width (typically 45″ or 60″)
Total fabric width: 115 inches (from previous calculation)
Desired length: 25 inches
Seam allowance and hem: 3 inches
Total fabric needed: (115 + 3) × (25 + 3) = 118 × 28 = 3,304 square inches
For 60-inch wide fabric: 3,304 ÷ 60 ≈ 55 inches or 1.5 yards
Best Length for a Pleated Skirt
- Mini: 14-17 inches
- Knee-length: 19-22 inches
- Midi: 25-32 inches
- Maxi: 33-40 inches
For a versatile option, consider a knee-length pleated skirt. It’s suitable for various body types and can be dressed up or down for different occasions.
For someone 5’6″ tall, a knee-length pleated skirt might measure 21 inches from waist to hem, hitting just at or slightly below the knee for a flattering silhouette.
Formula for a Knife Pleat Skirt
The formula for a knife pleat skirt is similar to the pleated skirt formula, with slight modifications:
Total fabric width = Waist measurement + (Number of pleats × Pleat depth × 3)- Waist: 32 inches
- Desired number of pleats: 24
- Pleat depth: 1 inch
Total fabric width = 32 + (24 × 1 × 3) = 32 + 72 = 104 inchesThis calculation shows you’ll need approximately 104 inches (or 2.9 yards) of fabric for your knife pleat skirt.
