The conversion table
Tennis rating conversion, country by country
You arrive with a French classement, a German LK, a UTR, or the level your Tokyo tennis school put you in. Deuce reads them all against one spine, the US NTRP scale, and this is the table it uses. Every band is an estimate with its source stated, and nothing on it outranks a played match.

The table, and your place on it
The converter
Start from your number
UTR is gender-blind while NTRP pools are not, so the same UTR reads differently for men and women.
Deuce seeds you at
4.0
Reads as NTRP 3.5 to 4.0
Source: several sources agree
The seed reads the strong end of the band, never the middle. Your first challenge is unrestricted, so a seed one band high costs you one match, and after a handful of confirmed results your imported number stops mattering.

Approximate by design, and endorsed by nobody. Researched August 2026 from federation rulebooks and published conversion charts; every cross-system band is fuzzy by about half an NTRP step either way. A ↓ in a header marks a scale that runs backwards: lower is stronger. A cell reading none means the system has no grade at that standard.
02
How to read the table
Each row is one band on the NTRP scale, 1.0 for a first racket through 7.0 for the touring professional. Read across for the grades that usually sit at that standard in each system.
01
Three quirks catch people. WTN and ITN run backwards: lower is stronger, and 40 is the beginner end of a WTN. France, Italy and Germany also count down toward their best players. And UTR is gender-blind while NTRP pools are not, so the same UTR reads differently for men and women. Deuce uses gender-specific UTR bands when it knows which apply.
02
A cell reading none means the system has no grade at that standard. Spain's categorías exist only for ranked tournament players, so a casual Spanish club player usually holds no federation rating at all. Korea's amateur divisions stop below the professional tier.
03
The bands overlap on purpose. No two of these systems measure the same thing on the same population, and any cross-system band is fuzzy by about half an NTRP step either way. Treat a row as a neighborhood, not an address.
03
What Deuce does with your number
Whatever you bring seeds your placement, and the seed reads the strong end of the plausible band, never the middle. Bring a rating that could mean NTRP 3.5 or 4.0 and you are treated as a 4.0 until results say otherwise. The reason is plain: a system that pays people to stay unmeasured is a system that breeds sandbaggers.
The correction happens on court, not in the table. Your first challenge in a ladder is unrestricted inside your band under rule 5.4 of the rules, so a placement one band too high costs you one match. After that, the number you brought stops mattering entirely: your rung is decided by who you beat. How a ladder works covers what happens from there.
A national federation ranking is the one input that never converts. A rank position depends on how many players the federation ranks: number 400 in Spain and number 400 in Malaysia are different players. Deuce stores the ranking, shows it to your organizer, and seeds you from your country's grade system or your own description instead.
The strong end of the band
A rating that could read 3.5 or 4.0 is seeded 4.0 until results say otherwise. The correction happens on court: one unrestricted first challenge, then your results on the ladder take over.
04
Where the numbers come from
The table was researched in August 2026 from federation rulebooks and published conversion charts, and every band carries one of four source grades:
Published by the scale's owner
The body that runs the rating printed the conversion itself. The ITN table is this grade.
14 bands in the dataset
Several sources agree
No single published table, but federation charts, club charts and coaching references land in the same place. Most of the table is this grade.
114 bands in the dataset
Chained
No direct table exists, so the band goes through a third system. The old LTA scale, retired in 2021, reaches NTRP only through charts that happened to list it.
34 bands in the dataset
Community estimate
Forum and club consensus only. The Korean divisions are this grade, and the table says so rather than dressing them up.
6 bands in the dataset
No governing body has endorsed this table, and it is not a substitute for a rating your league requires: if your league needs an NTRP, you still need an NTRP. The table is reviewed yearly, and the terms used here are defined in the glossary.

If yours is not listed
Bring it anyway. The signup form takes a club level in your own words ("second team", "B group", "club intermediate"), and deliberately wide self-description bands place you conservatively until you play. Great Britain needs no row of its own: since November 2021 your LTA rating is your WTN, so read the WTN column. Players from countries with no grade system at all answer a few plain questions instead, and the first match does the rest.

Where to go next
Playing
Bring whatever number you have, or none. Your first challenge is unrestricted, so a bad seed costs you one match.
Organizing
The table is an input for your level bands, not the decision. You can move any player, with the reason written to the public log.
