Quick Answer
Most people should not size down for Gymshark.
Gymshark generally fits true to size, but some compression-focused or seamless styles may feel tighter, which is why sizing down sometimes works for specific preferences.
From my experience working with activewear manufacturing, fit grading, and customer feedback loops, sizing confusion usually comes from fabric type and intended compression, not inconsistent sizing.
1. Why Gymshark Sizing Confuses So Many People
Gymshark offers:
- seamless collections
- compression fabrics
- body-hugging silhouettes

Official brand reference:
gymshark
These design choices make garments feel tighter than traditional gym wear — even when the sizing is technically correct.
Key insight:
“Tight” does not always mean “too small.”
2. Does Gymshark Run Small, True, or Large?
Overall sizing behavior:
- True to size: Most leggings, shorts, tops
- Snug by design: Seamless and compression styles
- More forgiving: Oversized or relaxed fits
My honest take:
Gymshark runs true to size, but feels tight if you’re not used to compression.
3. When You *Should* Size Down for Gymshark
Sizing down can make sense if you:
- prefer a very sculpted, compressive fit
- are between two sizes
- choose seamless leggings for aesthetic compression
- want a “locked-in” feel during workouts

Important:
Sizing down increases compression — it does not change length or rise.
4. When You *Should Not* Size Down
Do not size down if you:
- are new to Gymshark
- dislike tight waistbands
- want all-day comfort
- experience rolling or digging at the waist
- plan to wear leggings for long sessions
Reality check:
Sizing down too much causes:
- waistband roll-down
- sheerness when squatting
- reduced comfort
5. Size Down or Stay True? A Simple Decision Table
| Situation | Recommendation |
|---|---|
| First-time Gymshark buyer | Stay true to size |
| Seamless / compression leggings | Stay true or size down one |
| Between sizes | Choose based on compression preference |
| All-day wear | Stay true to size |
| Aesthetic sculpted look | Consider sizing down |
Key takeaway:
Fit preference matters more than brand sizing myths.
