Accurate & Scaleable, 3D Body Measurements
3D body measurements are standardized digital body dimensions generated from each scan using computer vision, machine learning, and AI. Captured in minutes on a smartphone or tablet, they provide consistent, repeatable body data at scale, enabling applications ranging from apparel fit and sizing to health, research, and manufacturing.
Precise 3D body measurements power better decisions across apparel, health, fitness, and research applications, and Size Stream delivers accurate measures consistently at scale. Each scan captures 240+ measurements automatically without manual input or specialized hardware. The platform adapts to how organizations operate, whether through mobile scanning or dedicated hardware without compromising accuracy. The same data layer supports each use case, from garment production to longitudinal health tracking.
One Platform.
Multiple Ways to Capture 3D Body Measurements.
Size Stream’s measurement ecosystem gives teams flexibility without sacrificing consistency. All three capture methods run on the same core computer vision, ML, and AI engine, meaning body measurement accuracy does not vary by device, operator, or environment.
Smartphone Scanning
3D body scanning using smartphone cameras. Mobile-first deployments that reach users anywhere, without specialized hardware.
Dedicated Hardware
Professional-grade scanning iPads for retail, clinical, and enterprise settings where throughput and consistency are critical.
SDK & APIs
Developer-ready integrations for embedding body measurement capability directly into existing platforms and products.
240+ Body Measurements Generated From a Single Scan
Size Stream automatically extracts a comprehensive set of body measurements from each scan. Every major body site is measured. Measurements are generated digitally without manual input, eliminating transcription error and operator variability. The output is a structured, consistent dataset that downstream systems can consume directly.
Measurements extracted per scan include:
- Standardized body measurements – 240+ circumferences, lengths, heights, breadths, and depths
- Derived body geometry – body volumes, surface area, proportions, and shape descriptors
- Derived health metrics – body composition and wellness indicators calculated from body data
- Application-ready data – structured outputs for apparel, health, research, and enterprise analytics
Accurate Body Measurement Technology Across Industries
Size Stream’s body measurement platform is industry-agnostic by design, functioning as a foundational data layer that separates measurement capture from downstream applications. Organizations across apparel, health, fitness, weight loss, and research apply the same body data to different workflows.
Measurements captured through the platform support:
- Fit and sizing systems
- Health and body composition analysis
- Standardized anthropometric research
- Custom garment and production workflows
Technical teams can activate body measurement data for a single application or combine it across multiple Size Stream solutions, the same scan data powers each use case.

Enterprise-Ready Deployment and Integration
Size Stream is built for deployment at enterprise scale. Consumer-facing and professional-grade setups are both supported. White-labeled and branded implementations allow organizations to embed body measurement capability within existing products. Data handling meets enterprise security requirements throughout.
The Foundation for Every Downstream Body Data Application
Body measurements are the starting point for fit, health insight, and production workflows. Size Stream structures raw scan data into consistent, integration-ready measurement sets that connect directly to downstream systems without additional transformation. Organizations that standardize on Size Stream reduce integration complexity and build more intelligent applications on top of trusted, repeatable data.
Frequently Asked Questions
How accurate is 3D body scanning?
3D body scanning achieves measurement accuracy that manual methods cannot replicate consistently. Size Stream uses computer vision, ML, and AI models trained on validated body scan datasets, with results falling within centimeters of reference measurements across body sites. Precision holds across operators and environments because the technology eliminates the variables that affect tape measures: operator skill, body positioning, and tape tension. For a peer-reviewed comparison of 3D scanning and manual anthropometry, see the Graybeal et al. study published in the British Journal of Nutrition.
How many measurements does a body scan capture?
A single Size Stream scan captures 240+ body measurements automatically, covering circumferences, lengths, heights, depths, volumes, all extracted in a single session. A typical manual fitting session captures 5 to 15 measurements and takes significantly longer. Size Stream’s automated measurements replace that process entirely, with greater consistency across sessions.
What is a 3D body scanner for measurements?
A 3D body scanner captures body geometry using cameras, sensors, or computer vision, then extracts dimensional data from the resulting body model. Size Stream supports three deployment types: mobile scanning on standard smartphones, dedicated hardware for retail and clinical settings, and SDK-based integration for existing platforms. All three deliver the same structured measurement output, governed by the same AI engine.
