This tool is simply wonderful! Taking measurements and photographing them was a pain point for me. The measurements are fantastic, and if I need to adjust, it's super easy to do. Laying flat, measurements are spot on. Great app, thank you!

Luxury buyers want PROOF. The label scanner captures brand tags, size labels, and care tags perfectly. I include everything in my listings, builds trust and eliminates 'is this authentic?' questions. My return rate is under 2% because buyers know exactly what they're getting.

The ghost mannequin shots transformed my listings overnight. Professional presentation without hiring models or renting studio space. Items that sat for weeks now sell in days. The ROI is insane, this feature alone paid for itself 100x over.

Everything you need to know about Size AI and professional garment measurements.

Size AI is an iPhone app that measures garments, scans labels, and creates studio-quality product photos and listing descriptions, built for fashion sellers and brands.

Using iPhone LiDAR, it captures up to 12 measurements per garment in 0.92 seconds to about 5 mm (1⁄5 inch) typical accuracy, then turns that data into ready-to-list photos and descriptions for wherever you sell.

More than 10,000 fashion sellers use Size AI, with over 1 million measurements captured and a 4.9 out of 5 rating from 2,301 reviews.

Size AI is free to download. The free plan includes 10 scans and 3 Photo Studio photos every month, with no credit card required.

Paid plans start at $9.99 per month and include every feature: LiDAR measurements, label scanning, Photo Studio, listing descriptions, and one-tap export. Higher tiers add more scans and images as your volume grows.

For marketplaces and high-volume operations, custom plans are available. See full pricing.

Best accuracy comes from LiDAR on:

iPhone Models:
• iPhone 12 Pro / Pro Max
• iPhone 13 Pro / Pro Max
• iPhone 14 Pro / Pro Max
• iPhone 15 Pro / Pro Max
• iPhone 16 Pro / Pro Max
• iPhone 17 Pro / Pro Max

iPad Models:
• iPad Pro 11" (2020 and later)
• iPad Pro 12.9" (2020 and later)

These models include LiDAR for our best accuracy, typically ~5 mm (about 1/5 inch). Size AI also works without LiDAR on iPhone 11 and later, with typical accuracy around ~9 mm (about 3/8 inch).

See: Capture Guide

TrueShape™ creates professional garment visualizations that show true-to-life proportions with clean backgrounds. Unlike generic templates, TrueShape™ reflects your garment's actual shape and measurements, not an approximation.

Clean backgrounds. Clear shapes. Exactly what buyers need to see.

See: TrueShape Guide

AI Photo Studio turns one flat-lay photo into two kinds of shot. Ghost Mannequin produces clean, invisible-mannequin product images in front, three-quarter, and side views. Model Shots place the garment on an AI model matched to your audience (men's, women's, kids').

No photoshoot, no studio. Both modes generate in seconds from the same capture.

See: Photo Studio Guide

90+ garment types across 9 categories, including:

Pants • Jeans • Shorts • Skirts • Jackets • Blazers • Hoodies • Sport Coats • Vests • T-Shirts • Polos • Dress Shirts • Tank Tops • Long Sleeves • Sweaters • Dresses • Boxers • Underwear • And more

From everyday basics to formal wear, Size AI measures it all.

See: Supported Garments Guide

Size AI delivers ~5 mm (about 1⁄5 inch) typical accuracy with LiDAR. Without LiDAR (iPhone 11 and later), typical accuracy is around ~9 mm (about 3⁄8 inch). For the most accurate results:

• Lay garment flat on a solid surface
• Ensure good, even lighting
• Capture at a straight 90° angle above the garment

For step-by-step guidance on achieving perfect measurements, view our in-app tutorials and best practices guides.

See: Measurement accuracy tips

Point your camera at any garment label. Size AI automatically captures:

• Brand, model, and item number
• Size information (primary and secondary)
• Complete fabric composition with percentages
• Stretch estimate (based on spandex/elastane content)
• Care instructions with all symbols
• Manufacturing details (made in, season)

The AI analyzes fabric composition to estimate stretch level. You can edit any captured information and add custom notes.

Works on faded labels, vintage tags, and labels in any language, returned in English.

See: Label Scanner Guide

Size AI builds descriptions from your actual garment data, not generic AI descriptions that you might see with other tools.

Your LiDAR measurements, scanned label, and garment photo are all analyzed together. Our AI model detects color, pattern, construction details, and fabric composition, then writes a structured listing with item details, condition notes, formatted measurements, and care instructions, as well as useful information for the shopper about a given brand.

Every description is SEO optimized for the platform you sell on: eBay, Poshmark, Grailed, Mercari, Depop, Etsy, Shopify, Amazon, and more. Tone, character limits, and keywords adapt automatically to appeal to shoppers search intent. No generic filler or AI slop, that turns away shoppers. Every sentence is factual, searchable, and built from the garment itself.

For fashion stores and eRetailers, Online Store mode generates clean product pages with bulleted sections, ready for Shopify, WooCommerce, or any storefront. Select your platforms, set your seller profile once (shop name, shipping, policies, language), and generate ready-to-post listings in one tap across 20 languages.

We analyzed thousands of high-converting listings across every major platform and eCommerce site. We learned what buyers respond to, what drives sales, and what gets ignored, then built that into how our AI writes every description.
