The assembled lengths agree
The pattern waist is 78.0 cm. Its target difference is 0.0 mm, and the waistband differs from the joined waist by 0.0 mm.
Basic shorts pattern
Create a shorts pattern from your measurements
Generate a free printable shorts block from your waist, hips, rise, outseam, inseam, thigh, and hem measurements. Choose regular, relaxed, culotte, or short proportions and download the custom front, back, and waistband as A4 PDF, copyshop PDF, or SVG.
Calculated draft
This shorts pattern is a calculated base draft based on the measurements and settings you enter.
Always sew a test garment, check crotch depth, seat fit, waist position, thigh comfort, and leg opening before cutting final fabric.

The generator checks the assembled waist, waistband, side seams, and inseams. Front and back crotch curves remain different because they shape different parts of the body.

Checks performed by the generator
Front and back are within tolerance
The front side seam is 46.3 cm and the back is 46.2 cm. Their difference is 0.75 mm within the 2 mm construction tolerance.
Equal inseams, shaped crotch curves
The inseam difference is 0.0 mm. The front crotch curve is 29.5 cm and the deeper back curve is 30.5 cm.

Measurements
Shorts measurements
Check the shorter pants-block logic behind shorts: rise, crotch curve, thigh opening, inseam, hem, and darts.
MeasurementsPants measurements
Understand waist, hip, rise, inseam, outseam, knee, hem, darts, and ease before generating a pants block.
ConstructionSeam and hem allowances
Read solid seam lines, dashed cutting lines, construction seam allowance, hem allowance, curves, and corners.
Pattern details
Shortened pants block
Shorts use the same base logic as pants but with a shorter inseam and more visible crotch-to-hem transitions.
Front, back, waistband, thigh opening
The critical areas are rise, crotch curve, inseam, side seam, thigh width, waistband, and hem.
Waist, hips, rise, inseam, thigh, hem
Short inseam values make curve smoothness and thigh opening especially important.
Smooth inseam and balanced sides
Check that the inseam flows smoothly, side seams match, waistband follows the waist, and hem allowance is correct.
Shorts pattern guide
A printable shorts block calculated from your measurements
The generator drafts coordinated front, back, and waistband pieces using your body, rise, and length measurements. Use these notes to choose the leg shape, allow enough movement, and print the pattern accurately.
Front, back and straight waistband
The download contains front and back shorts pieces, a straight waistband, waist darts when selected, seam and hem allowances, grainlines, thigh and hip guides, and a 5 × 5 cm print test square.
Waist, hips, rise, thigh and length
Waist and hips establish the upper block; rise and inseam control the crotch and finished length. Thigh and hem circumferences determine leg room and silhouette.
Regular, relaxed, culotte or short
Presets offer useful starting proportions for everyday, loose, wide, and shorter styles. All measurements and ease settings remain editable before the pattern is recalculated.
Coordinated seams and crotch levels
Front and back are constructed around shared waist, hip, thigh, and hem levels, with corresponding inseams and side seams checked for sewing compatibility.
Check sitting ease and leg opening
Test the block in similar fabric and check rise depth, seat room, waist position, thigh ease, and leg opening while standing, walking, and sitting.

Who, how, and when
Drafting logic by Nastix Design
This generator is maintained as application code: measurements are converted into vector geometry, related seams are measured numerically where the construction requires it, and the same geometry is used for preview, SVG, copyshop PDF, and tiled A4 PDF.
Generator content and output workflow reviewed 13 July 2026. A generated block remains a fitting starting point; verify measurements, print scale, fabric behaviour, and a test garment.
Common questions
Custom shorts pattern FAQ
Is the custom shorts sewing pattern free?
Yes. Enter your measurements, preview the generated pieces, and download the shorts pattern as A4 PDF, copyshop PDF, or SVG without purchasing a fixed-size pattern.
Does the shorts generator use standard sizes or my measurements?
Presets provide starting proportions, but the final waist, hips, rise, length, thigh, hem, ease, and dart geometry is recalculated from the values you enter.
Which shorts styles can I generate?
Regular, relaxed, culotte, and short presets set useful starting proportions. You can edit the inseam, thigh, hem, ease, waistband, darts, and allowances for a custom result.
How much ease should a shorts pattern have?
The required ease depends on fabric, silhouette, and activity. Start with the selected preset, then verify hip, seat, thigh, and sitting comfort in a test garment before cutting final fabric.
How should I print the A4 shorts pattern?
Print at actual size or 100% with fit-to-page disabled, then measure the 5 × 5 cm test square before assembling the tiled pages.
