Reading a racket spec sheet: what each line says and what it leaves out
Weight and grip code, balance, flex, stringing advice and string pattern, read on three real maker pages.
Why read the sheet line by line
A racket page looks complete, but each line has its own meaning and some lines are simply missing. Reading three pages from the same maker side by side shows what you can rely on and what you must check elsewhere. We used the pages of one entry racket and two stiffer models from the US site of one maker, read on 9 November 2026. This is not a ranking and not advice to buy.
The lines you will meet
- Weight & Grip. One code that holds two facts. On these pages "4UG5" means the weight class 4U and the grip size G5. The 100ZZ page lists two codes, "3UG5, 4UG5", so one page covers two versions with different weights.
- Weight. Two of the pages give "4U (83g avg.)". "Avg." means an average for the class, not the weight of the racket in your hand. The 100ZZ page gives no weight in grams at all.
- Balance. Two pages say "Head Heavy". The entry racket page does not list a balance at all.
- Shaft Flex. The maker's own words: "Hi-Flex", "Stiff", "Extra Stiff". No number is given, so the scale is the maker's and cannot be compared with another maker's.
- Stringing Advice. "4U 20-28lbs", "20-28lbs", "21-29lbs". It is advice from the maker, tied to a weight class on the entry page.
- String Pattern. "22 X 21" on all three pages. The pages do not explain the notation.
- Length. "10mm Longer". The pages do not say longer than what.
- Player Type. "Beginner" or "Intermediate / Advanced". It is the maker's marketing label, not a measure.
What the laws fix, and what they do not
Law 4 of the BWF Laws of Badminton, edition in force 26 April 2025 limits only the frame: at most 680 mm long and 230 mm wide, stringed area at most 280 mm by 220 mm. Weight, balance, flex and tension are not in the laws. So every line in the list above is the maker's choice of words, and it stays a description, not a standard.
A method to use on any sheet
- Split the weight and grip code into its two parts.
- Note which lines are given and which are missing. A missing balance means you cannot compare balance for that racket.
- Treat "avg." as a class average.
- Compare flex words only inside one maker's range.
- Read the stringing advice as a range given by the maker; keep it with the weight class it is attached to.
- When a line is not explained on the page, say so rather than guess.
