Quick Answer: Resistance band color is not standardized across brands — a red band from one company can be lighter or heavier than a red band from another, so color should be treated as a within-brand reference only, never a cross-brand comparison.

You grabbed a ‘medium’ band assuming it would feel roughly the same as your old set’s medium. It didn’t. That’s not a manufacturing defect — it’s the color system working exactly as inconsistently as it’s designed.

Why isn’t there a universal band color standard?

Because no regulatory body enforces one — each manufacturer sets its own color-to-resistance mapping based on their own material and thickness choices. Two brands’ ‘medium’ bands can differ significantly in actual pull weight.

How should you actually judge a band’s resistance?

Check the labeled resistance range in pounds or kilograms, which most reputable brands do include, rather than relying on color alone. If no numeric range is listed, test the band’s stretch resistance directly rather than assuming based on color.

What should you do when switching between band brands?

Treat every new brand’s set as unlabeled until you’ve personally tested each band against a familiar exercise — don’t assume your usual ‘green equals medium’ assumption carries over.

FAQ: Resistance Band Color Questions, Answered

Is there any brand where color actually is standardized?

Some brands are consistent within their own product lines, but there’s no agreement across brands industry-wide.

How can I test a band’s resistance without lifting equipment to compare?

Stretch it to a known length (like your own arm span) and gauge relative effort compared to a band you already know well.

Should I buy bands based on color from reviews I’ve read?

Use reviews for general quality and durability, but verify actual resistance level from the listed pound range, not the color mentioned in someone else’s review of a different brand’s set.

TL;DR:

• Band color is not standardized across manufacturers — treat it as brand-specific only
• Check the labeled resistance range in pounds, not color, when comparing bands
• Test new brands against a familiar exercise before assuming equivalent resistance
• A review mentioning color from a different brand doesn’t transfer to your set

Color is a within-brand shortcut at best — the pound range is the number that actually matters.
