Compare racket weights with the setup recorded
Separate a published average from a scale reading, and note the strings and grip wrapping before comparing two rackets.
Identify what the published number describes
Keep the exact model name, weight code, handle size and source with your notes. A published average and a reading for one racket answer different questions.
For example, Yonex lists both the ASTROX 77 PLAY and the ASTROX 70 as 4U, with an average of 83 g and G5 or G6 handle options. Those entries do not promise that every individual racket, with your chosen strings and wrapping, will weigh exactly that amount.
Check which condition the manufacturer's weight refers to. If the page does not explain it, ask the maker or retailer and keep the condition marked unknown until confirmed.
Describe the racket as it is
For each racket, note whether it has strings, the string reference if known, the original or replacement grip, any overgrip and any added tape or weight. If you cannot identify a layer underneath the wrapping, write unknown.
Remove the cover and loose packaging for a racket-only reading. Keep the playing setup intact: do not cut strings, strip a grip or alter the frame just to imitate a catalogue condition. Your note should describe the racket you would actually use.
Take a reading that you can describe
With the owner's permission, use the same suitable scale for both rackets and follow its instructions. Check the unit and zero, and support the whole racket on the weighing surface without a part touching the table or a hand. If it cannot sit securely, ask a shop with suitable equipment instead.
Let the display settle, then lift and replace the racket to check whether the reading repeats. Record the displayed value, unit and setup. Repeated readings do not establish the scale's accuracy. If they vary, record that variation rather than choosing the most convenient number; do not invent extra decimal places.
Keep a small difference in context
Here is a fictional example, unrelated to the two Yonex models: racket A reads 91 g with its strings and an overgrip; racket B reads 89 g with its strings and replacement grip. The displayed difference is 2 g, but the setups differ.
You can say that A gave the higher reading in those recorded conditions. You cannot use that difference to calculate the frames' weights without the strings and grips, or assign a standard weight to an accessory you did not weigh. Equal total readings would not establish equal balance or the same feel in motion either.
Use five questions before drawing a conclusion
- Have I recorded the exact model, weight code and handle size for each racket?
- Do I know the condition behind the published figure, or have I marked it unknown?
- Have I recorded the strings and wrapping, including anything I cannot identify?
- Were the readings taken in the same unit and with a method the scale can support?
- Am I comparing the recorded complete setups, without claiming to have measured the frames separately?
Keep these notes alongside a permitted trial in familiar conditions. Describe how each setup feels separately from what the scale displays. If the setups differ, retain that limitation instead of turning the smaller number into a recommendation.
