UTR Ranking Explained

August 27, 2018


UTR is a rating system that provides a single, unifying language and standard for tennis players across ages, geography, gender and economics. It’s an algorithm-based system for tennis that allows anyone to identify, measure, track and develop the level of a player. The UTR system is powered by over 7 million match results, across 700 thousand players in over 200 countries.


What is a UTR? Why should I have one?

UTR (Universal Tennis Rating) is a number that provides a real and accurate measurement of skill level. A player’s UTR is a number between 1.00 and 16.50.


One match result is all it takes to receive a projected UTR. After approximately five matches, the rating becomes official. As matches are played and entered into the system, a player’s UTR will increase or decrease over time as per the following methodology.


How is it calculated?

For each match, the algorithm calculates a match rating and a match weight for each player. A player’s UTR is the weighted average of up to 30 of his/her most recent match ratings. Only matches within the last 12 months count toward a player’s UTR.


Calculating Match Rating

Two metrics are used to calculate match rating. The first metric is the UTR difference between opponents. The second metric is the competitiveness of the match, as determined by the percent of total games won.


Given the UTR difference, the algorithm expects a certain percent of total games won. The player who performs better than the algorithm’s expectation will see their match rating go up while the other player’s match rating will go down. When one player’s match rating increases, the other player’s match rating decreases by the same amount.  


Calculating Match Weight

The following factors are used in the match weight calculation:


Format – As the match format increases in length, more weight is given. A match with a three-set format receives more weight than a match with an eight-game pro set format.


Competitiveness – As the UTR difference between players increases, less weight is given. For example, imagine a player with a UTR of 6.00. A match played against an opponent with a UTR of 5.00 or 7.00 receives more weight than a match played against an opponent with a UTR of 4.00 or 8.00.


Reliability – As the reliability of the opponent’s UTR increases, more weight is given. A match played against an opponent who competes often and thus has a reliable UTR receives more weight.


Time Degradation – As prior matches get older, less weight is given. Since the algorithm is a representation of current form, it gives more credit to matches played within the last few months.


I won my most recent match. What will happen to my UTR?

The algorithm focuses on percent of games won. If a player wins a higher percent of games than the algorithm’s expectation, their match rating goes up. Likewise, if a player wins a lower percent of games than expected, their match rating goes down. Factors other than your most recent match also impact changes in UTR (see next question).


What factors determine whether my UTR goes up or down?

The biggest factor that determines a UTR increase or decrease is a new match being added to a player’s record. However, this is not the only factor. Your oldest match falling off (because it became older than 12 months or was bumped off when a new match was added) can also have an impact. Another factor is time degradation. As prior matches move down the list, they receive less weight, so the weighted average of match ratings and match weights can change.


Is it possible for my UTR to go up or down, even though I haven’t played a new match?

Yes. Since the algorithm is a dynamic system that recalibrates every night, there may be small fluctuations in UTR. This is more common for players who recently joined the system. As more matches are added to a player’s record, their UTR becomes more stable. There are also small fluctuations in the match weights of a player’s existing matches that can affect the rating even while not playing. For example, time degradation will slowly decrease the weights of existing matches.     


For matches with a large UTR difference, can the higher-rated player still increase their UTR?

Yes. If the higher-rated player performs better than the algorithm’s expectation, his/her match rating goes up.


Do some matches not count towards my UTR?

The algorithm excludes matches in which a) a player withdraws before the match starts, b) the match starts but neither player wins at least four games (due to a withdrawal/retirement), or c) there is a UTR difference of more than 2.50 and the higher-rated player wins as expected. These excluded matches still show up on the player profile but are not used in the rating calculation.


Why does the algorithm exclude matches with a UTR difference of more than 2.50?

As the difference in UTR increases, so does the likelihood the higher-rated player wins the match easily. Our data indicates matches with a UTR difference of more than 2.50 are almost certain to be a blowout. Results like these are not indicative of either player’s skill level and are excluded by the algorithm.  


What if I have played fewer than 30 matches within the last 12 months?

That’s perfectly fine. If you have played only 10 matches within the last 12 months, the algorithm will use those 10. 30 is simply the maximum. If you have played 40 matches within the last 12 months, the algorithm will use the 30 most recent matches.


Why does my player profile show more than 30 total matches?

Many profiles show a longer match history, but only the most recent matches (those with a UTR ball icon next to the score) are used in the calculation of your rating. Matches without an icon are either a) too old, b) a withdrawal, or c) outside the 2.50 cutoff for UTR difference.


Why does my player profile show more than 30 icons?

This occurs when the 30th most recent match was played on the same day as the 31st most recent match. The algorithm does not try to determine which one to keep, so it keeps them both. They will fall off together when the next match is added.      


I don’t play very often. Can I still have a UTR?

Absolutely. One match is all it takes to get a “projected” rating. After approximately five matches, your rating becomes reliable. A projected rating is shown as a (P) on the player profile.


What is a projected rating? How many matches does it take to go from a projected to a reliable rating?

The algorithm needs approximately five results before it can calculate a reliable UTR. Ratings based on fewer than five results are not yet fully reliable, so are considered “projected”.  A projected rating is shown as a (P) on the player profile.


What matches are included in the UTR calculation?

Most matches you play will be included in your UTR rating.  This includes most high school matches, most USTA tournament matches and all UTR tournament matches.


High school matches are reported to UTR by the two coaches.  USTA reports all sanctioned tournament matches.  And of course UTR sponsored tournaments are included.  You don’t have to do a thing.  They’ll all be reported for you. 


Is it a valid ranking system?

UTR has proven to be good measurement of players' relative skills.  It's not 100% accurate in predicting results, because there are always intangibles that affect a match.  And players are hopefully always improving.  But look at the results from our recent match.  UTR rankings correctly predicted every singles match except one.  And in that match the two rankings were close enough to make it a toss-up.



How do I sign up?

A player profile is a webpage where a players rating, match history, and preferences are stored. Every player at MyUTR.com must claim or create a player profile.

You'll create a player profile during sign-up if you're new to tennis or don't have any scores recorded in our system.


You'll claim a player profile if you already have some play history online. Your player profile may already exist, but you'll need to claim it in order to make changes and customize.


So how do you claim your profile?

Go to MyUTR.com

  1. Click Get Rated at the top-right corner of the page

  2. Enter your email address and a password and click “Sign Up With Email”

  3. Enter your profile info! Note that if you’re signing up for your child, this information should be their own as each child needs their own account at MyUTR.com

  4. Click “Continue as a Player”

  5. This next part is really important! You (or your child) could already have a player profile at MyUTR.com - now you need to claim it. Click “Yes, this is me” on the information that matches you and claim your profile.

    1. If you see a message that says the profile has already been claimed, STOP! Your player profile has already been claimed. This normally isn't a case of a bandit grabbing up your profile - typically another family member made a profile for you (or your kiddo) and is a step ahead. You can do one of the following:

      • Ask your family members if they claimed the profile and continue to use the UTR account that has claimed the profile.

      • Contact our support team HERE for help claiming the correct profile.
