Choosing the right size is the most important step when buying a spandex bodysuit.
Spandex is designed to fit close to the body, but the wrong size can affect comfort, movement, and appearance.
This US size guide explains how to choose correctly.
Why Sizing Matters with Spandex
Spandex stretches, but it is not unlimited.
A correct size allows the fabric to stretch evenly and return to shape without discomfort.
Sizing too small often causes pressure points, while sizing too large can lead to sagging.
Key Measurements You Should Check
Height
Height is critical for bodysuits.
Torso length affects how the suit sits on shoulders and hips.
If you are taller than average,sizing up often improves comfort.
Weight Range
Weight helps estimate how the fabric will stretch on the body.
Most size charts combine height and weight for accuracy.
Bust / Chest
The bust or chest measurement affects upper-body tension.
Too much tension here often causes discomfort during movement.
Waist & Hips
Spandex adapts well to curves, but the suit should lie flat without digging into the skin.
Visible pressure marks are a sign of incorrect sizing.
Typical US Spandex Size Chart (Reference)
XS–S: Petite height, lighter weight range
M: Average height and build
L: Taller or curvier body types
XL–XXL: Extended height or broader proportions
Always compare brand-specific charts before ordering.
Should You Size Up or Down?
Sizing up is often recommended if:
• you are between sizes
• you are taller than average
• you prefer comfort over compression
Sizing down is only recommended if the brand explicitly suggests it.
Fit Differences by Spandex Style
Not all spandex fits the same.
Shiny spandex usually offers more flexibility. Leohex-style bodysuits feel tighter and more second-skin. Wetlook materials stretch less and feel firmer.

Common Sizing Mistakes to Avoid
• Choosing size based only on weight
• Ignoring height and torso length
• Expecting zero wrinkles during movement
• Assuming tighter always looks better
A balanced fit always looks better than forced tightness.
Final Size Check Before Buying
Before ordering, ask yourself:
• Does the size match my height range?
• Will the fabric stretch evenly?
• Do I want comfort or compression?
If comfort matters, choose the safer size.
