AI Tech Pack Measurement Charts: Automated Points of Measure Across All Sizes
How AI tech packs generate measurement charts with proper points of measure, tolerances, and grading across your full size range — automatically.
The measurement chart challenge
Measurement charts are the most critical and most time-consuming section of any tech pack. A single garment may have 15-25 points of measure (POM), each needing a base size measurement, tolerance range, and graded measurement for every size in the range. For a 6-size run, that is 90-150 individual measurements.
An AI tech pack from Skema3D generates the complete measurement chart automatically — all points of measure, base size values, graded values, and tolerances — based on your garment type, fit, and size range.
Standard points of measure by garment type
Different garment categories require different measurement points.
Points of measure by garment category
| Garment Type | Key POMs | Total POMs |
|---|---|---|
| T-shirt/Tee | Chest, waist, body length, sleeve length, shoulder, neck width | 12-15 |
| Hoodie/Sweatshirt | Chest, waist, body length, sleeve length, shoulder, hood height, hood width | 15-18 |
| Pants/Jeans | Waist, hip, thigh, knee, leg opening, inseam, outseam, rise | 14-18 |
| Dress | Bust, waist, hip, body length, shoulder, skirt length, armhole | 15-20 |
| Jacket/Coat | Chest, waist, body length, sleeve length, shoulder, across back, collar | 18-25 |
Tolerances in AI tech packs
Every measurement needs a tolerance — the acceptable range of variation from the specified value. Tolerances account for fabric shrinkage, cutting variation, and sewing variation.
- Critical measurements (chest, waist, hip): ±0.5 inch or ±1 cm
- Length measurements (body, sleeve, inseam): ±0.5 inch or ±1 cm
- Detail measurements (collar, cuff, pocket): ±0.25 inch or ±0.5 cm
- Small details (button placement, label position): ±0.125 inch or ±0.3 cm
- Stretch fabrics: wider tolerances (add ±0.25 inch to standard)
How to read an AI-generated measurement chart
Skema3D's AI tech pack presents measurements in a grid format: measurement names in the left column, size columns across the top, and graded values in each cell. The base size (usually M) is highlighted. Tolerances appear as ± values next to each measurement.
Each measurement includes a diagram reference — a letter or number that corresponds to a point on the flat sketch showing exactly where and how to measure. This diagram-measurement connection prevents measurement method confusion between your specifications and the factory's interpretation.
Customizing AI-generated measurements
If you need to adjust the AI-generated measurements, tell Skema3D which measurement to change and by how much. The AI recalculates graded values across all sizes while maintaining proportional consistency. You can also change the grading increment — for example, 'grade chest at 1.5 inches per size instead of 2 inches.'
