Smash Speed Lab
Find Your Power Ceiling.
Most players think swinging harder = faster smash. It’s not that simple. The Smash Speed Lab analyses your wrist snap timing, contact point, racket head speed, and follow-through — and tells you exactly where your power is leaking. Enter your numbers, get your breakdown.
Calculators & Finders.
Answer five questions — playing style, level, preferred shot type, budget, and weight preference — and get a specific racket recommendation with the reason why.
Measure from the middle crease of your palm to the tip of your ring finger. Enter the measurement in cm or inches and get your grip size in L1–L5 and 4⅛–4⅝ inch formats.
Enter racket head size, string material, and playing style. Get a recommended tension range in lbs and kg, with an explanation of how higher vs lower tension changes power and feel.
Enter your body weight, session duration, and intensity level — casual rally vs competitive singles — and see how many calories a pickleball session burns compared to other sports.
Convert between US, UK, EU, and CM shoe sizes for court sports footwear. Accounts for the half-size up rule most badminton and squash players use for extra toe room.
Analyse your badminton smash by entering contact point, grip type, and swing path. The tool calculates your theoretical shuttle speed and flags the biggest limiter in your power profile.
Some Questions Need a
Result, Not a Guide.
A 1,500-word article about grip size is useful. A tool that gives you “your grip size is L3 / 4⅜ inches” in 20 seconds is more useful. Both have a place — the tools page is where you get the direct answer.
Every tool on this page runs in your browser. Nothing to install, no account needed.
Tools give you a number or a recommendation — not “it depends.” Context is added after the result, not before.
Each tool was created because players kept asking the same question in guides and comment sections. These are the answers in interactive form.
