T-shirt Size Guide

MULTIVERSITY / FIT GUIDE

Start with the fit you want, then confirm it against the specific product measurements.

Multiversity uses more than one T-shirt fit and construction. Do not assume every tee uses the same blank, fabric weight, or measurements.

Quick Fit Guide

Use this as your first decision. Then check the individual product page before ordering.

INTENDED FIT

Want the tee to fit as designed?

Choose your regular size when the product is described as oversized or boxy. That usually preserves the intended shoulder width, body volume, and drape.

CLOSER FIT

Want less volume?

Consider sizing down one size only after comparing the garment measurements with a T-shirt you already own and like.

BETWEEN SIZES

Not sure which way to go?

Use chest width and body length instead of the size letter alone. Choose the measurements closest to the way you want the tee to sit.

Important: this is a general fit guide, not a universal Multiversity size chart. Product-specific measurements always take priority.

SOURCE OF TRUTH

Use the Product Page First

The individual product page is the source of truth for available sizes, fit notes, material, construction, and any product-specific measurements. If a product page includes a size chart, use that chart before this general guide.

How to Measure a T-Shirt

01

Lay it flat

Use a T-shirt you already like. Lay it flat on a smooth surface without stretching the fabric.

02

Measure chest width

Measure straight across from armpit to armpit. This is the garment width, not your body circumference.

03

Measure body length

Measure from the highest shoulder point down to the bottom hem, then compare both numbers with the product chart.

FIT LANGUAGE

What the Terms Mean

Regular

A more conventional body width and length with less intentional volume.

Relaxed

More room than a regular fit without the stronger proportions of a true oversized cut.

Oversized

Designed with extra volume through the body and often wider or dropped shoulders.

Boxy

A wider, straighter silhouette often paired with a shorter body length for a more structured proportion.

HEAVYWEIGHT FIT EXAMPLE

Oversized Heavyweight T-Shirts

Multiversity heavyweight tees use structured cotton and intentionally roomy silhouettes, with product-specific details such as boxy bodies or drop shoulders.

Choose your regular size for the intended oversized fit. For a closer fit, consider sizing down only after checking the garment measurements on the product page.
