Player-measured ball-bounce frequencies from the community Blade Speed Comparison Sheet. Brands don't publish an official Hz, and the same model varies a little from blade to blade — so each blade shows the range players actually measured, not a single spec.
One scale for everything on this page: 800–2,350 Hz, soft to stiff — the full range of the database, so even the fastest blades draw. Each bar is the range players actually measured for that blade, the dot is its average, and the shaded columns are the speed classes. The shading is the site's own table blue at six depths — pale for soft, deep for stiff, with OFF in the exact blue of the site's buttons — so a bar's position and shade always agree. Tap any row for the blade's full detail.
Most blades cluster between 1,200 and 1,600 Hz. The long tail above ~1,700 Hz is mostly balsa and 1-ply hinoki blades — their readings run high for their feel, so compare them with care. The scale runs the full way to 2,350 Hz so the fastest blades in the database, up to 2,325 Hz, draw in full.
Tap a blade for its full detail. Tap Compare on two blades to put them side by side.
Measured the same way this app measures: ball bounced on the bare blade, loudest peak of the sound. Use the ranges to see where a blade sits — not as an exact spec.
Data: the Blade Speed Comparison Sheet — created and maintained by h0n1g on the MyTableTennis forum, from an idea by slevin, with measurements contributed by forum members including arg0, shaibu, Azv and patrickhrdlicka. Snapshot of the sheet as updated May 18, 2026. Classes (DEF to OFF+) follow the sheet's own rating hypothesis, based on each blade's average. Full credit and thanks to h0n1g and every player who submitted a measurement.
A searchable database of community-measured blades is on its way — 975 blades and 1,559 player measurements, each with its measured frequency range, average and weight, so you can see exactly where a blade sits before you buy it.
It will cover every brand in the community sheet, with filters for brand, speed class and frequency, a graph of where blades land, and side-by-side comparisons.
Measuring is live right now: bounce a ball on your bare blade and get its frequency in Hz.
Thirty seconds, no spectrum app to decode: remove the rubbers, hold the handle loosely, bounce a ball on the centre of the bare blade, and read the loudest peak of the sound. Higher Hz means a stiffer blade; lower means softer and more flexible.
The method comes from the forums, where players used general-purpose spectrum apps: Advanced Spectrum Analyzer PRO was removed from Google Play in September 2024, and Spectroid shows you a full live spectrum with no blade answer — the most common forum question is “I downloaded the app, but I don't know what I'm looking at.” This page does the peak-finding and the interpretation for you, in the browser, with nothing to install.
The loudest peak is the blade head's membrane vibration. It tracks stiffness and surface hardness at a light impact, and correlates loosely with speed — it does not measure flex, dwell, or how the blade catapults on a hard hit. Two blades at the same Hz can still feel different, and balsa or 1-ply hinoki blades read far higher than they feel. Use Hz to compare similar blades, and treat it as a rough guide before buying — which is exactly how the players who built the database describe it.
Repeatability is your quality check: bounce a few times and re-measure. Readings within a few Hz of each other mean your grip and bounce are consistent. Weight matters too — heavier blades measure higher, and the same model can vary from specimen to specimen.
A gentle, clean bounce or a drop from about 10–15 cm onto the centre is enough. You're listening for the blade's ring, not testing its power — a soft, centred bounce gives the clearest peak.
Yes: the frequency is the loudest peak of the sound's spectrum. Older apps made you find and mark that peak yourself on a live graph that moved too fast to read; this app holds the peak and reports it as one number.
On the community scale, 1,400–1,600 Hz is OFF territory — stiff and fast-feeling for most players. Plenty of players love blades in the 1,400–1,450 Hz range for the extra snap; above that, expect a hard, unforgiving feel unless the construction says otherwise.
Wood varies. Players have measured the same model (Viscaria is the famous case) anywhere from about 1,370 to 1,550 Hz across different years and weights — a heavier specimen usually measures higher. That's why the database shows a range and a measurement count, never one magic number.
You can, but the number won't be comparable: rubber lowers the frequency a lot, and every rubber lowers it differently. The database — and this app — are built on bare-blade readings.
What your Hz means in playing terms. The bands below are the community scale from the Blade Speed Comparison Sheet — the same one this app and the database use. A second, simpler forum scale exists; where they disagree, this page says so rather than pretending there is one official line.
| Class | Frequency | Typical feel |
|---|---|---|
| DEF | Under 1,000 Hz | Soft, slow, maximum control |
| ALL | 1,000–1,100 Hz | Soft and controlled — a classic beginner band |
| ALL+ | 1,100–1,250 Hz | Balanced all-round play |
| OFF− | 1,250–1,350 Hz | Noticeably crisper, still forgiving |
| OFF | 1,350–1,550 Hz | Stiff and fast — where most carbon blades sit |
| OFF+ | Over 1,550 Hz | Very stiff, very fast, least forgiving |
The feel labels on the Measure page run on the same idea: Soft under ~1,200 Hz, Balanced to ~1,400, Stiff to ~1,550, Very stiff above that.
An older, simpler forum scale puts the lines lower: ALL under 1,150 Hz, OFF− 1,150–1,300, OFF 1,300–1,500, OFF+ over 1,500. Same blades, same readings — just different borders. If a forum post calls a 1,320 Hz blade “OFF” and this chart calls it OFF−, you're looking at the two scales, not a disagreement about the blade.
Heavier blades measure higher — players have reported 80–100 Hz from a 3 g difference in the same model. One forum model adjusts for it: for a 5.6 mm blade with a 60 g head weight, the class borders land near ALL 1,017 / ALL+ 1,174 / OFF− 1,312 / OFF 1,438 / OFF+ 1,553 Hz. A heavy blade near a border deserves the benefit of the doubt; a light one likewise. The database lists each blade's average weight for exactly this reason.
Most blades in the database land between 1,200 and 1,600 Hz, and many players settle on a personal band they like — 1,400–1,450 Hz is a commonly quoted sweet spot. Measure your current blade, then use the database to find what sits just above or below it.
