Table tennis blade frequency FAQ
How hard should I bounce?
Drop the ball from 10–15 cm onto the center of the face. A gentle, clean bounce gives the sharpest peak.
Which peak is the blade frequency?
The loudest peak in the 800–2600 Hz range. This app locks onto that peak automatically.
What does the frequency number actually tell me?
Frequency (in Hz) directly measures surface stiffness and ball rebound speed on light impact. Higher frequencies mean a stiffer, faster blade with shorter dwell time, while lower frequencies indicate more flex, longer dwell, and softer touch.
What is considered a normal or average blade frequency?
Most modern table tennis blades fall between 1100 Hz and 1500 Hz. All-wood blades typically range around 1150–1300 Hz (ALL+ to OFF−), inner-carbon blades sit around 1300–1400 Hz (OFF− to OFF), and outer-carbon blades usually sit above 1400 Hz (OFF to OFF+).
Why do two copies of the same blade differ?
Wood density and weight vary from blade to blade (a Viscaria can span 1327–1508 Hz). Heavier copies read higher.
Can I measure with rubbers on?
No. Rubber damps the pitch heavily and unevenly, so only bare-blade readings are comparable.
I know my blade's frequency but don't have a recording. How can I add it?
You do not need an audio recording to contribute! If you already measured your blade or know its acoustic frequency and weight, submit it here. It goes to the shared database review queue and appears only after approval.
About Blade Frequency
A free web tool that measures table tennis blade frequency. Bounce a ball on the bare blade and the app analyzes the sound. The loudest peak is your blade’s frequency in Hz. Higher Hz means a stiffer blade.

Your audio and readings stay on your device
Microphone audio and uploaded files are processed locally in your browser using the Web Audio API in this version of the app. No audio is recorded to a server, transmitted, or stored.
Blade Frequency does not require sign-up, does not use tracking cookies, and does not sell or share personal data with third parties. Fonts are served from this site, not fetched from a third party.
Three things are saved in your browser's local storage: your language (bf-lang), your light or dark theme (bf-theme), and your recent readings (bf-history, up to 30, on your device only). Nothing else is stored on your device by this app.
When you submit a blade, its name, Hz reading and weight are sent to the shared Blade Frequency database for review. They appear in the public database only after approval. Your audio is never sent anywhere.
Blade submissions are processed by Cloudflare Workers and stored in Cloudflare D1; this site is hosted on Cloudflare Pages. Feedback sent by email goes to [email protected]. The site runs without Turnstile — submissions are protected by rate limiting and human moderation instead.
Terms of use
Simple terms for using Blade Frequency
Blade Frequency is a free acoustic utility and reference guide provided "as is" without warranties of any kind.
Hz readings depend on bare-blade wood variation, ambient noise, and device microphones. Use readings as a practical reference, not a factory guarantee.
You are responsible for handling your blade, rubbers, and phone safely while bouncing a ball or removing rubbers.
Reference measurements are compiled from community acoustic contributions for players to compare equipment.
Blade Frequency is operated by Atmosfyr. Contact: [email protected].
These terms were last updated on 13 November 2026.
Submitted blade names, frequencies and weights are kept in the shared database review queue and, once approved, in the public database. Approved measurements stay until removed. To request removal of a measurement you submitted, email [email protected] with the blade name, frequency and weight; removals are handled manually by the operator.
Blade Frequency is intended for users aged 13 and over. If you are under 13, please use it with a parent or guardian.
Community Guidelines
Fair readings keep the database useful for everyone
- Measure bare blades only — rubber damps the pitch, so only bare-blade readings are comparable.
- Share honest readings — submit only blades you measured yourself, with the correct frequency and weight.
- Don’t copy other sources — don’t copy ratings, descriptions, or prices from other sites or databases.
- Be respectful — no spam, misleading blades, or abusive content in submissions or feedback.
- Submissions are reviewed — readings you send go to the shared database review queue and appear only after approval.
