Flat Sketch to Size Chart: No Manual Calculation
Transform your technical flat sketches into complete, graded size charts automatically. No spreadsheets, no formulas, no manual calculations—just upload and export.
The Manual Calculation Problem
Fashion designers spend hours manually calculating grade rules, filling spreadsheets, and cross-checking measurements. One formula error can cascade through the entire size range, causing costly production mistakes.
✏️ From Sketch to Spec Sheet in Minutes
Every garment starts as a sketch—whether it's a quick hand drawing, an Illustrator flat, or a CAD technical drawing. But turning that sketch into a production-ready size chart has traditionally required:
- Manually measuring or estimating base dimensions
- Setting up complex Excel formulas for grading
- Calculating each size based on grade rules
- Double-checking every number for errors
- Formatting into a presentable spec sheet
Now, you can skip all of that. Upload your flat sketch and get a complete, graded size chart in minutes.
⚙️ How Automatic Sketch-to-Size-Chart Works
Upload Your Flat Sketch
Export your sketch from Illustrator, CAD, or scan your hand drawing. PNG and JPG work best. The cleaner the sketch, the better the results.
AI Identifies Garment & Measurement Points
The system recognizes your garment type and automatically identifies all relevant measurement points (chest, length, shoulder, sleeve, etc.).
Set Base Size & Grade Rules
Choose your base size (typically M) and customize grade rules. Use presets for US, EU, or Asian markets, or define your own increments.
Generate & Export Complete Size Chart
Instantly receive a fully graded size chart. Export to Excel, PDF, or copy directly into your tech pack.

💡 Pro Tips for Best Results
Use High-Contrast Sketches
Black lines on white background work best. Avoid gray or colored backgrounds that might confuse edge detection.
Keep Proportions Accurate
Even stylized flats work, but more accurate proportions yield better measurement predictions.
Include Front & Back Views
For complex garments, uploading both views helps the AI understand construction details better.
Review & Adjust Base Size
Always verify the base size measurements before generating the full grade. Small adjustments here affect all sizes.
