D5585-21 – Standard Test Method Technical Guide
📐 Scope and Figure Type Definition
ASTM D5585‑21 provides standardized tables of body measurements for the Adult Female Misses Figure Type, covering the extended size range of 00 through 20. These tables serve as a baseline for designing apparel, allowing manufacturers to account for fabric type, ease for body movement, styling, and fit. The standard defines a primary reference height of 5 ft 5 in. (165 cm), representing approximately 65% of the average USA population.
A critical feature of this revision is the formal definition of two distinct body silhouettes: Curvy and Straight. These classifications are determined by specific differences in the waist, high hip, hip seat, thigh, and mid‑thigh girths, directly addressing the need for diverse fit models within the Misses size range.
⚙️ Data Sources and Incremental Grading Methodology
The measurement tables in D5585‑21 were compiled from a comprehensive review of modern anthropometric data. Key sources include the U.S. Department of Commerce’s Voluntary Product Standard, the CAESAR anthropometric study, the Size USA study, and 3D body‑scan documentation from Alvanon Inc. A major focus of the 2021 revision was the analysis of incremental growth rates at critical body points—the bust, waist, high hip, and hip/seat—to ensure smooth, logical transitions between consecutive sizes. Furthermore, the standard now includes standard points of measure for hand length, hand width, foot length, and foot width to support the development of authentic ASTM 3D Missy Avatars.
✅ Thorough Data Validation: To verify the proposed measurements, Alvanon Inc. created a full set of 3D avatars in the Misses size range 00 through 20, encompassing both Curvy and Straight silhouettes. This provides a direct visual and digital reference for the standard data.
📊 Key Body Measurement Tables
The following table provides a representative excerpt of the Straight figure type body measurements. Note that the values listed are for the body, not the garment, and must be combined with appropriate ease allowances for end‑product fit.
| 🟦 Misses Size | 📏 Bust (in) | 📐 Waist (in) | 🎯 Hip/Seat (in) | ⚡ High Hip (in) |
|---|---|---|---|---|
| 00 | 31.5 | 24.0 | 34.0 | 30.5 |
| 2 | 33.5 | 26.0 | 36.0 | 32.5 |
| 6 | 35.5 | 28.0 | 38.0 | 34.5 |
| 10 | 38.0 | 31.0 | 40.5 | 36.5 |
| 14 | 41.0 | 34.0 | 43.5 | 39.5 |
| 18 | 44.5 | 38.0 | 47.0 | 42.5 |
| 20 | 46.5 | 40.0 | 49.0 | 44.5 |
For the Curvy silhouette, the waist girth is reduced while the hip/seat and thigh girths are increased relative to the Straight baseline at the same size, reflecting the differential rates of change at key body points.
⚠️ Unit Compliance Requirement: Per Section 1.3 of the standard, the values stated in SI units or inch‑pound units are to be regarded separately as standard. The values in each system are not exact equivalents; combining them may result in non‑conformance with the standard. Each system shall be used independently.
