Technium Foundry Sizing Chart | How to determine T-Shirt size

TECHNIUM FOUNDRY, LLC SIZING CHART

Understanding T-Shirt Sizing - The Essential Guide

A comprehensive sizing chart is crucial for confident online t-shirt shopping, as it bridges the gap between vision and reality. The most important elements include precise measurements for chest width, shirt length, and sleeve length in both inches and centimeters.

Pay special attention to whether the brand follows traditional sizing (S, M, L) or numerical sizing, and note any indicators that a style runs "true to size," "slim fit," or "oversized." Gender-specific cuts have distinct proportions—men's shirts typically have broader shoulders and longer torsos, while women's feature more tapered waists. Material composition significantly impacts fit; cotton tends to shrink slightly, while blended fabrics maintain their shape.

For maximum satisfaction, always measure a well-fitting shirt you already own and compare these measurements to the chart rather than relying solely on your usual size designation. Remember that international sizing varies considerably—an American medium might be a European large—so never assume size equivalency across different regions or brands.


When an astronaut decides that zero gravity is just another word for "perfect wave conditions." Our "Cosmic Surfer" design features the ultimate space athlete who looked at the laws of physics and said "rad, but what if we added a surfboard?" Rendered in retro-tech gold tones that would make both NASA and vintage arcade games proud.

The tagline "Gravity Can't Hold Us Down" might be the most literal interpretation of irony since an astronaut first figured out that falling is just surfing through spacetime with style. It's what happens when you cross Kelly Slater with Neil Armstrong and give them an energy drink.
