Elo vs DUPR
DUPR — Dynamic Universal Pickleball Rating — is the rating standard for pickleball, used across clubs, leagues and tours worldwide. Elo is a general-purpose formula that works for anything with a winner and a loser.
They get compared because they do the same arithmetic job. They are answering quite different questions.
What Elo is
An open, published formula, applicable to any head-to-head activity. Two ratings produce an expected score, the result moves both by the difference between expectation and outcome, and the K-factor sets the size of the move. Nothing about it is specific to any sport. The full explanation is here.
Because it is generic, an Elo rating means something only within the pool that produced it. Your 1400 in a group of eight friends and someone else's 1400 in a different group are unrelated numbers that happen to look alike.
What DUPR is
DUPR works on the same underlying principle — real match results continuously refining a rating — but everything around it is purpose-built for one sport:
- It is a single global standard, so one player's rating is comparable with any other player's.
- It rates singles and doubles separately, because they are close to different sports.
- It uses a fixed, sport-meaningful scale (roughly 2.0 to 8.0) that players and organisers already read fluently.
- It takes score margins into account, not just who won.
- It is portable: it follows you to any DUPR-affiliated club, league or tournament, and is used for bracketing and seeding.
That last point is the whole value. A rating that only exists inside one app is a talking point. A rating recognised across a sport is infrastructure.
Side by side
| Elo | DUPR | |
|---|---|---|
| Scope | Any activity | Pickleball |
| Scale | Arbitrary, implementation-specific | One global standard, ~2.0–8.0 |
| Comparable between venues | No | Yes |
| Singles and doubles | One pool unless separated deliberately | Rated separately by design |
| Uses score margin | No | Yes |
| Who it is run by | Nobody — it is a formula | A single governing organisation |
Which one you want
If you play competitive pickleball and want a rating that gets you into the right bracket at a tournament in another state, you want DUPR. It is the standard, it is free for players, and no general-purpose tool can substitute for a number the whole sport already recognises.
A general-purpose tool like Custom Elo Games is for the competitions that sit outside any sport-wide standard — which is most of them. The Thursday night group at your local court that never enters a sanctioned event. The mixed games night where pickleball is one of four things you play. The office ladder, the club comp, the family tournament at Christmas.
These two things coexist perfectly well, and plenty of people want both: a DUPR rating for sanctioned play, and a private leaderboard for the regular group where the only thing at stake is bragging rights until next week. If that is you, you can see how a single result moves two ratings on the Elo calculator, then set up a Game for the group DUPR was never going to cover.
