Our Mission & Story
Standardizing Apparel Sizing
One Fit at a Time
We build free, mathematical fit tools and verified measurement charts to eliminate online sizing confusion and reduce global apparel returns.
Why TShirtSizeChart.com Was Created
Online apparel shopping has made discovering custom prints, designer garments, and everyday wardrobe essentials easier than ever. However, sizing inconsistencies remain the single largest point of friction in e-commerce. Over 30% of online clothing purchases are returned, with ill-fitting size labels driving the overwhelming majority of those returns.
A "Medium" from a European fashion retailer fits vastly differently than an American boxy streetwear cut or an athletic performance tee. At TShirtSizeChart.com, our mission is to eliminate arbitrary letter designations and replace them with verified, concrete physical measurements in both inches and centimeters.
Precision Data
Every chart on our platform is mapped to verified finished garment specifications, including chest circumference, length, shoulder width, and sleeve dimensions.
Smart Calculators
Our dynamic algorithms factor in wearing ease allowances (Slim, Regular, Relaxed, Oversized) to provide personalized, borderline-aware recommendations.
100% Free & Open
No paywalls, no forced registrations, and no cluttered ads. Just instant, authoritative sizing tools built for consumers, merchants, and custom apparel printers.
