Quick answer: blue dot for beginners and juniors, red dot for improvers, single yellow for most UK club players, and double yellow only for strong league and competition players who hit hard enough to keep it warm. In cold winter halls, drop one dot level.
Walk into any UK leisure centre on a Tuesday night and you will find two players sweating through a match with completely the wrong ball. It is the most common, and cheapest to fix, mistake in club squash. This squash ball guide explains what the coloured dots mean, why a double yellow will ruin your game if you are not ready for it, how cold British sports halls change things, and which balls are worth buying in 2026.
What the dots on a squash ball actually mean
The coloured dot is a speed and bounce rating, not a quality marker. A more expensive ball is not a "better" ball — it is a slower one. The dot tells you how much the rubber will bounce once warm, and how quickly it gets there.
- Blue dot — fastest, highest bounce, warms up almost instantly. For absolute beginners and juniors.
- Red dot — fast with a good bounce, slightly slower than blue. The natural next step for improvers.
- Single yellow dot — slow, low bounce, needs a few minutes of hitting. The club standard.
- Double yellow dot — extra slow, lowest bounce, demands a properly warm ball and player. The competition standard.
The better you get, the harder you hit, and the more heat you put into the ball. Match the dot to the player, not to the price tag.
Blue and red dot: the balls that keep beginners rallying
If you have played fewer than about twenty sessions, start with a blue dot. The bigger bounce buys you the extra half-second you need to get your feet in position and swing properly. Handing a beginner a double yellow is the fastest way to teach bad habits. Red dot is the bridge: once rallies regularly reach six or seven shots, it slows things down without punishing you. Juniors and returning players also enjoy red dot squash far more than a tournament ball.
Single yellow vs double yellow: the club player's real decision
The double yellow is the World Squash Federation competition standard, so it carries status. But status does not win matches. A double yellow needs five to ten minutes of hard rallying to reach its designed bounce. If your rallies are typically under ten shots, or you play a friendly game with breaks, it will never warm up and you will over-hit everything. The single yellow reaches playing temperature far faster, gives longer rallies and still rewards accuracy. Play league or county squash with long rallies? Move to double yellow. Play twice a week for fun and fitness? Single yellow will give you better squash almost every time.
Cold UK sports halls change everything
A December session in an unheated hall is a different physics problem to a heated club court in July. Cold rubber does not bounce, and a cold double yellow is effectively a beanbag. Practical rule: drop one dot level in winter. Keep the ball in a pocket between games, and give it four or five minutes of straight drives before the first point. Carrying two dot levels costs a few pounds and saves a session.
Racketball uses a different ball
Squash 57 (still widely called racketball) is played on the same court with a larger, bouncier ball and a shorter racket. A squash ball will not work for racketball, and vice versa. Check your club board before you buy, and browse our squash range if you need both.

How long a squash ball lasts
As the rubber fatigues it loses bounce permanently. A regular club player using a double yellow typically gets six to twelve hours of court time before performance drops. Replace it when it feels dead even after a long warm-up, the surface goes shiny, or you see a hairline crack — cracked balls fail without warning, usually at 8-8 in the decider.
FAQs
Which squash ball should a beginner use?
Blue dot, then red dot once rallies regularly reach six or seven shots.
Single or double yellow dot for club squash?
Single yellow for most club players. Double yellow only if you hit hard enough, with long rallies, to keep it warm.
Why does my squash ball not bounce?
It is too cold or too slow for your level. Warm it up properly, or drop one dot level, especially in winter.
The bottom line
The right squash ball matches your rally length and court temperature, not what the professionals use. Get that one choice right and your squash improves immediately, for less than the price of a court booking. Unsure? Our team plays the game and is happy to advise.
