This question usually comes up when a league or event asks for a rating you do not have. The two systems are run by different organizations, use different results and serve different purposes. If you need the basics first, read what UTR is and how NTRP levels work.
UTR vs NTRP: the main differences
| Feature | UTR | NTRP |
|---|---|---|
| Run by | UTR Sports | USTA |
| Scale | 1.00 to 16.50. Higher is stronger. | 1.5 to 7.0 in half-point steps. Higher is stronger. |
| What you see | A rating number that can change often | A half-point level. The dynamic rating in hundredths is not published. |
| Updates | Recalculates every 24 hours | Published once a year in December. Dynamic ratings run nightly for local play but stay hidden. |
| Results used | Up to 30 recent matches from the last 12 months. Standard UTR includes casual play, practice and self-posted scores. Verified UTR uses vetted events only. | USTA League and, depending on your section, NTRP tournaments and other adult leagues. Ladders and non-sanctioned events do not count. |
| What moves it | Your share of games compared with the expected share | The match score compared with the expected outcome, not directly the win or loss |
| Doubles | Compares team averages. Both partners move by the same amount. | Singles and doubles results feed one rating. Both partners are treated the same. |
| Who it groups | One scale regardless of age or gender | Levels used within USTA League divisions. Published conversions treat men and women differently. |
| Getting started | A questionnaire gives a temporary range. One match gives a projected rating, and about five make it reliable. | A self-rate questionnaire. At least three valid matches can produce a year-end computer rating. |
| Main uses | Verified UTR: recruiting, event entry, seeding and line-ups. Also UTR Flex Leagues. | USTA League eligibility and NTRP tournaments |
The two systems share one idea: each compares your result with an expected result. So in both systems you can win a match and see your rating fall, or lose and see it rise.
UTR to NTRP conversion: published charts side by side
No single official conversion exists. We found none issued as official by the USTA or UTR Sports, and the commercial site Bounce states that no rating organization publishes an official cross-system table. The charts below were made for different purposes, and they disagree. All figures are approximate and were read in November 2026.

Who published each chart, and why
- UTR Sports placement chart: a recommendation for placing unrated players in Flex Leagues, offered as guidance on where your UTR may be.
- UTR Sports scale chart: a wider chart on the same page. The ranges here were read from its dots.
- UTR Sports How UTR Works page: a chart it describes as a U.S. case study. It gives approximate NTRP bands for UTR 1 to 3 and UTR 4 to 7, and none above that.
- USTA NorCal table: published by one USTA section for its Generation Gap event. It is not a national USTA conversion.
- Tennis360 formula: quoted on the same USTA NorCal page, which does not reconcile it with its own table. We calculated the figures above from it: men's NTRP x 2.2, and (women's NTRP - 0.5) x 2.2.
- Bounce estimate: a commercial converter that labels its values approximate. Its main table has no men's and women's split, though it says women's NTRP maps about half a level lower in UTR. For UTR 6.00 it shows NTRP 4.0 with a range of 3.0 to 5.0.
Why the charts disagree, and how far apart they are
A men's 4.0 runs from UTR 4 at the bottom of the UTR Sports scale chart to 8.8 by the formula. A women's 4.0 runs from 3 to 7.7. UTR Sports alone publishes three charts that do not match. Part of the reason is that the charts have different purposes. Another is the shape of the systems: NTRP puts a wide band of players under one label, and the USTA says a 3.01 and a 3.49 are both published as 3.5 although a typical match between them would be 6-0, 6-0. No single UTR number can describe that whole band.
So treat any chart as a first guess at who might be a fair opponent. It does not tell you your rating.
Which rating matters for you?
| Your situation | Rating that counts | What to do |
|---|---|---|
| Joining a USTA League team | NTRP | Use your valid computer rating, or self-rate. Do not use a conversion as your rating. |
| You have a UTR and must self-rate for USTA League | NTRP | Judge yourself against the USTA level descriptions and give your full tennis history. If you are unsure between two levels, the regulations tell you to choose the higher one. |
| Joining a UTR Flex League with no UTR | UTR | Give your NTRP and tennis history at registration. UTR Sports uses them to place you. |
| Entering an event on UTRSports.net | UTR | Answer the Get Rated questionnaire, then build a real rating with matches. |
| Aiming for college tennis | Verified UTR, and possibly WTN | UTR Sports says college coaches look at Verified UTR. The USTA also describes the World Tennis Number as a tool for college coaches. Ask each program. |
| USTA junior tournaments | WTN | The USTA calls WTN the exclusive rating for USTA Junior Tournaments. |
| A club or local league with its own rule | Whatever it names | Ask which chart it uses and follow only that one. |
A better test than any chart: get the real number
If you keep needing a conversion, the better fix is to earn the other rating.
- For a UTR: play five full matches, best of three sets where you can, against opponents who compete often. About five results make the rating reliable, and longer formats and reliable opponents carry more weight.
- For a Verified UTR: make those matches verified events. UTR Sports says USTA League matches count, so league players may already have one. Check your profile for the blue checkmark.
- For an NTRP computer rating: play at least three valid matches in qualifying USTA leagues or NTRP tournaments your section has opted in, then wait for the December publication.
- To raise a rating you already have: read how to improve your UTR.
An estimate from an app does not replace any of these steps. TennisAI shows estimated NTRP and UTR numbers based on your video analyses. They are not official, TennisAI is not affiliated with the USTA or UTR Sports, and they should not be used for league entry.
Frequently asked questions
What UTR is a 4.0 NTRP?
There is no single official answer. For men, UTR Sports gives 5.0-6.99, 4-8 and 4-7 on its three charts, and USTA NorCal gives 6-8. For women, the same sources give 3-4.99, 3-6, 4-7 and 4-6.
What NTRP is a UTR of 6?
There is no official answer. The UTR Sports placement chart puts 5.0-6.99 at NTRP 4.0 for men and at 4.5 or 5.0 for women. Its How UTR Works page puts UTR 4 to 7 at about 3.5 to 4.5 for men and 4.0 to 5.0 for women.
Can I use my UTR to self-rate for USTA League?
Not as a direct conversion. USTA regulations say to consider your on-court performance, tennis background and other information, and to choose the higher level if you are unsure.
Is UTR or NTRP more accurate?
We found no independent test that compares them. They do different jobs: the USTA describes NTRP as a static yearly rating that suits a season-long competition, while UTR recalculates daily.
Do USTA League matches count toward UTR?
Yes. UTR Sports lists sanctioned adult league and tournament matches, such as USTA, among the results that count toward Verified UTR.
