How do I know what size compression shirt to buy?

Published in Compression Sizing Guide 4 mins read

To determine the correct size for a compression shirt, the general guideline is to select your regular clothing size and then consult the specific brand's size chart. The ideal fit also depends on your familiarity with compression wear and your desired level of compression.

Understanding Compression Sizing

Compression shirts are designed to fit snugly against your body, applying pressure that can support muscles, reduce vibration, and potentially aid recovery and performance. Achieving the right fit is crucial for comfort and effectiveness. Too loose, and you won't get the benefits; too tight, and it can be uncomfortable or restrictive.

Sizing Guidance Based on Your Experience Level

Your experience with compression clothing plays a role in finding your optimal fit:

  • For Experienced Compression Wearers: If you are accustomed to the feel and benefits of compression apparel, you might consider sizing down from your regular size. This can provide an enhanced level of compression, maximizing the supportive benefits.
  • For New Compression Wearers: If you are new to wearing compression clothing, comfort is often a primary concern. In this case, it's recommended to choose an in-between size (if applicable on a size chart) or even size up from your regular size. This approach allows you to gradually adapt to the sensation of compression while ensuring it remains comfortable enough for extended wear.

Essential Steps to Find Your Perfect Fit

Finding the right compression shirt size involves a few key steps to ensure a comfortable and effective fit.

1. Measure Yourself Accurately

Before looking at any size chart, take precise body measurements. For a compression shirt, the most important measurement is usually your chest circumference.

  • Chest: Measure around the fullest part of your chest, typically right under your armpits. Ensure the measuring tape is level and not too tight or too loose.

2. Consult the Brand's Size Chart

Every brand's sizing can differ, so always refer to the specific size chart provided by the manufacturer of the compression shirt you intend to buy. This is the most reliable source for sizing information.

Example Generic Size Chart (Always check brand-specific charts):

Size Chest (inches) Chest (cm)
XS 30-32 76-81
S 33-35 84-89
M 36-38 91-97
L 39-41 99-104
XL 42-44 107-112
XXL 45-47 114-119

You can often find these charts on the product page or a dedicated sizing guide on the brand's official website.

3. Consider the Intended Use

Think about what you'll be using the compression shirt for:

  • High-Intensity Workouts: For strenuous activities, a slightly tighter fit might be preferred for maximum support.
  • Recovery or Casual Wear: If you plan to wear it for recovery or as a base layer for warmth, a more comfortable, slightly less restrictive fit might be better.
  • Layering: If you intend to wear other layers over it, ensure the compression shirt isn't so bulky that it interferes with your outer garments.

Tips for a Great Fit

  • How it Should Feel: A compression shirt should feel snug, like a second skin, but not painfully tight or restrictive to your breathing or movement. You should be able to move your arms and torso freely without feeling constricted.
  • Check for Bunching: There should be minimal bunching or wrinkling, especially around the armpits or waist, as this indicates excess fabric.
  • Material Stretch: High-quality compression fabrics are designed to stretch significantly while maintaining their shape and compression properties. Don't be afraid if it looks small out of the package; it's meant to stretch to fit.

By following these guidelines and paying close attention to specific brand recommendations, you can confidently choose a compression shirt that offers optimal comfort and performance benefits.
