![]() Another rule of thumb is that typically ~70% of the rubber sheet will go onto your blade (~30% of offcut), so about 70% of each uncut sheet weight should be added to your blade weight (plus a few grams for glue/edge tape) to work out the total weight. It can be a little tricky to work out the area of a blade face, but as a guide, a typical blade face area is about 190sqcm, so you can use that as a starting point. Don’t forget to add a few grams for glue and edge tape, and don’t forget that the sponge thickness affects the mass of the rubber sheet too. Add the other rubber as well, plus the weight of the blade, and you’ll get a good estimate of the overall bat weight. ![]() So if you know the area of the face of your blade, you simply need to multiply this by this number and you’ll get a close estimate of the total weight. The last column in the table provides the weight of the rubber per square centimeter. The top left pull-down menu will allow you to show up to 100 entries on a page. Use ‘search’ to find any name (or part of a name)or number in any of the columns and it will list all the rubbers that contain that word or number. A click on any column will re-order the list according the column values. Use the table below to find the rubbers you’re interested in. How to estimate the mass from the data in the table? If you do happen to buy an oversize blade, this table can be useful to look up if the rubber sheets that you’re considering will fit your blade. Why is the size useful?Īlthough most rubber sheets are cut at the factory to easily fit a standard size blade, there are a lot of unusually shaped blades out there, some much larger than standard. Two heavy rubber can make a bat feel very top-heavy, and if you can’t get used to it, you’ll have wasted your money. This allows you to estimate the weight of a new bat before you decide on the rubber / blade combination. Since the weight of a bat is typically almost half contributed by the rubbers, and rubber weights vary a lot (from brand to brand and model to model), it’s important to have an estimate of the weight of the rubber. Although the weights of blades are usually indicated, the weight of the rubber is usually unknown. Most players have a preference for a certain weight of their table tennis bat. So both databases should be checked for information.Ĭredit goes to the members of OOAK Forum and more recently the MyTT forum for continuing to provide the data! His database still contains a large number of entries not contained in this one, but the database below will contain the latest entries from the community and my own additions, and it will continue to be updated. Since he was unable to continue updating the project for the time being, I have started this new database which is an extension of his, not a replacement. Great credit goes to Silver (aka Silvalis) who has long maintained a database of rubber masses here. This is a database of table tennis rubbers sheets, indicating their mass and size.
