A breakdown of the definition of throw angle by Greg Letts
One of the tenergy club member recently asked what is low, medium and high throw, so before I answer this question it is important to have a look at what google already has on offer to give us a definition of throw angle. OK I am searching now searching now and…..
Oh wow, the number 1 ranked explanation is by my mate Greg Letts, our About.com Guide! Great we are going to be in for a deep treat now.

Definition: The throw angle of a rubber is whether the rubber tends to ‘throw’ the ball higher or lower when making the same stroke.
- Totally agree with this first sentence.
Given the same return from your opponent, and the same stroke by you, a rubber that puts the ball in the net is considered to have a ‘lower throw’ than a rubber than puts the ball on the table. For the same circumstances, a rubber that puts the ball off the end of the table is considered to have a ‘high throw’.
- I’m not totally happy with this though. What lands on your opponent’s side of the table depends on your skill level and what you are used to. A ball going into the net could mean your rubber is too tacky or slow and will not reach their side. It could also mean your blade is too slow for the rubber. The most incorrect part of the explanation is the part about going off the end of the table.
- A ball will often go off the end of the table no matter which throw you use. It all depends on stroke. Low throw rubbers go off the table more because Low throw is considered faster with less spin. They are faster since they go from A to B in a straight line. But because they have less spin and can only draw a straighter line, the choices of ball placement are much less, and are pretty much confined to near the base line. Low throw rubbers are usually not recommended for players wanting to learn to loop. Low Throw rubbers are hard to loop onto the table because the rubbers a harder and has less spin to arc the ball. Low throw rubbers also must be taken from the height of the bounce to be attacked.
You will sometimes hear players talk about ‘degrees of throw’ – basically a rubber than puts the ball low has a low degree of throw, and vice versa. Generally, low throw rubbers have degrees of throw in the 30s, while 40-44 degrees of throw is roughly a medium throw rubber, and higher than 44 degrees of throw is typically considered a high throw rubber. These numbers are not exact, and may vary from manufacturer to manufacturer. This throw angle is not an exact science (contrary to what you might think from reading on the various forums!), but more of a comparative feel between different rubbers.
- What ever you do, don’t make a mistake of reading the degrees listed above as the degrees you find on a table tennis rubber packet. Every time I have ever heard the word degree used in numbers it has never been about throw angle. For throw angles we just say low, medium-low, medium, medium-high, high. Something like that. Any numbers as listed above are ridiculously misleading. The softer the sponge or the lower degrees of sponge hardness – for example a 30 degree sponge usually gives a higher throw angle degree. So when it says 30 degrees on the packet the throw angle is higher. So when you read on the packet 45 degrees, this is a harder rubber with a higher degree of hardness but a much lower throw angle.
- If you are not sure of which hardness to buy always go the middle path and don’t forget that your blade will also alter how it plays.
A rubber with a high throw is not better or worse than a rubber with a low throw, it is just different.
- Well said
Generally, low throw rubbers are considered to be easier to play with against topspin, while high throw rubbers are supposed to be able to lift backspin over the net more easily.
- Not so well said. Tenergy 05 rubber has an incredibly high throw angle and Tenergy 05 or 64 are the best counter topspinning rubbers on the market. Low throw rubbers are best know for their more hit or drive style of play and because they require the user to contact the ball at the top of the bounce, they are best suited to players very close to the table. Tenergy 25 is an example of that.
I would recommend a high throw rubber to a beginner before a low throw, especially if the beginner wants to learn to loop.
