Step-by-Step: Creating Your First Chart
Access the Generator

Choose Your Garment Type
Select from categories: T-shirts, Dresses, Pants, Jackets, Kids, Swimwear, etc.
💡 Tip: Or upload your own garment image for custom analysis.
Enter Base Measurements
Input measurements for your base size (usually M). Use your actual product measurements, not generic data.
💡 Tip: If unsure, use the generator's industry defaults as a starting point.
Select Size Range
Choose which sizes to include: XS-3XL, numeric (0-16), or custom labels.
💡 Tip: Match the size range your customers expect. Check competitor listings.
Generate & Review
Click generate. The tool calculates all sizes using industry grading. Review each measurement.
💡 Tip: Compare generated values against your actual samples if available.

Common Mistakes to Avoid
❌ Using Generic Measurements
Always measure your actual products. Generic charts from the internet won't match your items.
❌ Skipping the Review Step
Auto-generated values are a starting point. Always review and adjust based on your actual products.
❌ Missing Key Measurements
Include all measurements customers need. A t-shirt needs chest, length, AND shoulder—not just chest.
❌ No Measurement Instructions
Tell customers how to measure themselves. "Chest" means different things to different people.
❌ Low-Resolution Images
Export at high resolution. Blurry size charts look unprofessional and are hard to read.
Best Practices for Professional Results
✅ Measure Multiple Samples
Production varies. Measure 2-3 samples per size and use the average.
✅ Include Size Conversions
International customers need US/UK/EU equivalents. Generators add these automatically.
✅ Add "How to Measure"
Include diagrams or instructions showing where to measure.
✅ Use Both Units
Show inches AND centimeters. Don't make customers convert.
✅ Update Regularly
When products change, update charts. Old charts cause returns.
✅ Test Before Launch
Have someone else try using your chart. Is it clear? Complete?
