Shoulder seams within 1 mm
The front shoulder measures 118.0 mm and the fitted back shoulder 118.85 mm. Their difference is 0.85 mm, inside the generator’s 1 mm tolerance.
Generate a free printable front and back bodice block from your bust, waist, shoulder, front and back length, armhole, and neckline measurements. Adjust ease, waist shaping, darts, and armhole contouring, then download the custom block as A4 PDF, copyshop PDF, or SVG.
This bodice block is a drafting guide based on your measurements and selected settings.
We strongly recommend making a test version and checking the fit before cutting final fabric.
Real generated example
This front-and-back bodice example is generated on this page from the exact measurements below. The drawing is produced by the same drafting class used in the measurement, preview, and download workflow—not by a separate stock illustration.
The generator builds both half-patterns, adds bust, waist and shoulder shaping, then measures and automatically balances the joining shoulder and side seams before export.
Enter your own body measurements; this EU 38 starting set is shown only to make the calculation and checks transparent.
The front shoulder measures 118.0 mm and the fitted back shoulder 118.85 mm. Their difference is 0.85 mm, inside the generator’s 1 mm tolerance.
The complete front side seam is 185.02 mm and the back is 184.08 mm. Their 0.94 mm difference is inside the 1 mm sewing tolerance.
The generated full neckline is 33.0 cm and the combined front-and-back armhole is 40.6 cm, ready to reference when developing collars, facings or a sleeve.
Full-size front and back pieces divided across numbered A4 pages with alignment marks and a 5 × 5 cm test square.
Both bodice pieces on a large-format sheet generated from the same measured curves and seam allowances.

Pattern details
The bodice draft is a foundation for tops, dresses, sleeveless blocks, V-neck starts, and sleeve-based projects.
The key areas are shoulder, neckline, armhole curve, waist shaping, and vertical balance.
Small errors in shoulder or armhole depth can change sleeve compatibility and wearing comfort.
Check front/back balance, shoulder length, neckline shape, armhole curve, dart placement, and waist shaping.
Basic bodice block guide
A bodice block is a close-fitting drafting foundation rather than a finished garment pattern. This generator builds front and back pieces, shapes the bust and waist with darts, balances the seams, and adds printable construction allowances.
The printable draft includes front and back half-patterns cut on the fold, waist darts, a front bust dart, a back shoulder dart, neckline and armhole curves, grainlines, allowances, and a 5 × 5 cm test square.
Bust and ease establish the upper width; waist controls suppression and dart intake. Separate front and back lengths, shoulder length, armhole depth, and neckline depth establish vertical balance and the upper contour.
The shaping option distributes suppression between the side seam and darts. Armhole adjustment and contouring provide additional control for sleeveless or closer-fitting variations.
The generator measures the actual front seams, automatically fits the back shoulder and side seam to them within a 1 mm tolerance, and reports the resulting waistline and armhole lengths for review.
Use the block as a starting point for neckline changes, sleeveless bodices, fitted tops, dresses, style lines, and compatible sleeve development. Add design ease and construction details for the final garment.
Print at 100% with scaling disabled and verify the test square before cutting. Use tiled A4 at home, copyshop PDF for a full-size sheet, or SVG for controlled vector adjustments.
Who, how, and when
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
A basic bodice block is a close-fitting front and back foundation drafted from body measurements. It is used to develop tops, dresses, necklines, style lines, and other upper-body patterns.
Yes. Size presets provide starting values, but the final widths, lengths, darts, neckline, armholes, shoulders, and side seams are recalculated from the measurements and options entered in the form.
Yes. The front includes waist and bust shaping, while the back includes waist and shoulder shaping. Dart intake changes with the selected waist-shaping option.
The generated armhole length is available for sleeve development, but cap shape, ease, notches, fabric, and intended movement must still be tested. Use the sleeve block as a starting point and sew a test garment.
Print at actual size or 100%, disable fit-to-page scaling, and measure the 5 × 5 cm square before trimming and joining the tiled sheets.
