38.0 cm across the bicep line
The 32 cm bicep plus 6 cm ease produces a 38.0 cm sleeve width. The long-sleeve hem is calculated at 19.1 cm from the 17 cm wrist and part of the selected ease.
Basic sleeve block
Create a basic sleeve pattern from your measurements
Generate a free printable sleeve block from your arm length, bicep, wrist, elbow length, and sleeve-cap height. Choose a fitted, relaxed, short, or cap-sleeve direction and download the custom pattern as A4 PDF, copyshop PDF, or SVG.
Important fit note
This sleeve block is a drafting guide based on your measurements and selected settings.
We strongly recommend making a test version and checking sleeve fit and armhole compatibility before cutting final fabric.

Real generated example
From arm measurements to a full-size sleeve block
Live sleeve draftThis example is generated by the same drafting code used for downloads. It turns a 32 cm bicep, 6 cm of ease, a 58 cm arm length, and the remaining settings below into the one-piece sleeve shown here—not a stock illustration or a fixed-size pattern.

The preview, dimensions, allowances, notches, grainline, and 5 × 5 cm test square all come from one calculation. Sleeve-cap compatibility still depends on the bodice or dress armhole, so compare those seam lengths before cutting fabric.

What the generator calculated
A measurable sleeve cap
The cap rises 14.0 cm above the bicep line. Its two generated Bézier curves measure 48.0 cm in total; compare that seam length with the complete garment armhole and the intended cap ease.
Length and scale controls
The finished center length is 58.0 cm. The export also includes the selected 1 cm seam allowance, 3 cm hem allowance, and a 5.0 × 5.0 cm square for checking print scale.

Pattern details
Sleeve block with cap and guides
The sleeve draft includes the sleeve outline, cap curve, grainline, elbow or length guides, and hem direction.
Sleeve cap to armhole
The sleeve cap must match the armhole it will be sewn into; both curve length and shape matter.
Length, bicep, wrist, and ease
These values control movement, width, hem opening, and whether a cuff or open hem will work.
Bicep ease and cuff opening
Check bicep room, wrist or cuff compatibility, elbow placement, cap length, and print scale.
Basic sleeve pattern guide
A printable sleeve block shaped from your arm measurements
The generator uses arm length and circumferences, cap height, ease, and sleeve type to draft a symmetrical one-piece sleeve. Use these notes to measure accurately, check compatibility with the intended armhole, and print at full scale.
One-piece sleeve with construction guides
The export contains a complete symmetrical sleeve piece with sleeve-cap and underarm seams, grainline, bicep and elbow guides, hem line, selected allowances, notches, and a 5 × 5 cm print test square.
Arm length, bicep, wrist, elbow and cap height
Arm length and wrist set the lower sleeve; bicep plus ease controls upper-arm room. Elbow length positions the guide, while cap height controls the height and curvature of the sleeve head.
Long, relaxed, short or cap sleeve
Presets provide practical starting values for length, ease, and cap shape. Each measurement remains editable, so the sleeve is recalculated instead of scaled from a fixed-size pattern.
Check the sleeve cap against the armhole
A sleeve must sew into a specific bodice or dress armhole. Compare the sleeve-cap seam length with the complete front and back armhole seam, account for the intended ease, and adjust before cutting fabric.
Test upper-arm room and movement
Make a test sleeve in similar fabric and check bicep ease, cap height, shoulder mobility, elbow position, wrist width, and the direction of the grainline with the actual garment body.

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
Basic sleeve pattern FAQ
Is the custom sleeve pattern free?
Yes. Enter your arm measurements, preview the generated sleeve, and download it as A4 PDF, copyshop PDF, or SVG without purchasing a standard-size pattern.
Which measurements are needed for the sleeve block?
The main inputs are arm length, bicep, wrist, elbow length, and sleeve-cap height. You can also control bicep ease, sleeve length, seam allowance, and hem allowance.
Can I generate long, short, and cap sleeves?
Yes. Choose a basic long, relaxed, short, or cap-sleeve preset, then edit the length, circumferences, ease, and cap height for the intended garment.
Will this sleeve automatically fit any armhole?
No. Armholes vary by garment and size. Measure the complete front and back armhole seam, compare it with the sleeve-cap seam, and test the assembled sleeve before cutting final fabric.
How should I print the A4 sleeve pattern?
Select actual size or 100%, disable fit-to-page scaling, and measure the 5 × 5 cm test square before trimming and joining the tiled pages.
