Having precise t-shirt measurements on your store is vital—it contributes to your store’s credibility and customer satisfaction.

T-shirt sizes vary a lot from brand to brand, and that’s often confusing for shoppers. That’s why “how to measure a t-shirt” is one of the most commonly asked questions.

Providing accurate measurements lets customers know exactly what they’re getting and reduces returns, enhancing overall business efficiency.

So, if you’re selling custom t-shirts online, knowing how to measure them properly is a must. Here’s a simple guide to help you do it right.

Key t-shirt measurements

Precise measurements are the foundation for a good fit. These measurements determine how the garment drapes on the body and how happy your customers will be with the shirts they get.

You can find the length and width measurements of each shirt in the size chart on its product page.

Please note that product measurements are provided by our suppliers and may vary by up to 2″ (5 cm). We recommend ordering a sample of the shirts you want to sell and measuring them yourself.

When taking measurements, it’s important to lay the shirt on a flat surface so it doesn’t stretch or move around while you’re measuring.

Also, ensure you’re not pulling on the fabric because that will give you inaccurate numbers.

Here are the measurements people shopping online will appreciate and how to take them.
