FIDE vs Chess.com ratings explained

My chess.com rating is standard-1629,blitz-1653,& bullet-1420, & tactics-2027. What should be my fide rating? I'm an unrated.

My highest chess.com rating is almost 1400,but FIDE rating 1181!?

incredible, now that I'm taking my QBA (Quantitative & Business Analytics) I could somehow (yeah, only somehow) relate on these statistics -- cool and a great job done by @GagarinGambit! kudos bro!

Dis guy knows da wae

So a 1500 blitz rating on chess.com represents aproximately what FIDE rating with what standard deviation?

and also a 1500 rapid rating

The first post in this thread actually answers this exact question!

Pawsibbly.

hahaha....online players are weak....they not even know how to play chess...they are good because computer...wake up...play real chess...join real tournament

Impressive survey with sound background knowledge about statistics.

Good Job, OP.

Thanks for your accurate analysis.

Thank you very much.

Any update on the numbers? (the first analysis is 5 years old now...)

I'm not a mathematician, but even so, what I see looks very impressive. Players here have pointed out that young players improve rapidly and are almost always under rated.  What about older players on the downhill slide of being over 40 or 50 or 60? We're almost always over rated. I used to be a NM strength player when I was playing. Since I haven't played a serious tournament in over 30 years, I'm very over rated now.  USCF regular rating 2276, quick 2290 (based on 3 games) and blitz 2081 (based on 14 games). Chess.com daily 2122, rapid 1957 and blitz 2005. It seems to me that your initial research should have included age as well.

Thanks allot... Learnt lot about rating... Good work...

I'd like to add some of my thoughts to this interesting discussion. We can see that some users have puzzle rating higher even by 1000 points than their FIDE and 500 points higher than their standard. I can think of a few reasons for this phenomena. One is that they are doing worse with physical chess pieces (they are used to computer 2D pieces). Travelling to different places and environments to play FIDE games can be tiring and stressful, thus they are not as relaxed and concentrated as in their living room logged to a chess site, sipping tea from a mug and making their new record score. Often they are kids, and their chess skills in 2 months can improve dramatically, but they don't play for FIDE often. In online chess, on the other hand, their real rating is updated instantly. As for the older users who used to be chess masters and lose their skills with age, it seems that they are a minority in online chess. Rarely there will be cases of people playing regularly, whose ratings constantly deteriorate. Online chess is dominated by quickly improving kids and teens. Finally, there is a controversial conclusion that puzzle rating doesn't matter as much in real chess as other aspects of the game such as defense, attacking plan, opening and endgame knowledge, time management, concentration, patience, creativity, etc.

For now,

Online : 1400 Blitz and rapid, 1850 tactics

Fide : 1055 Classical (Chessboard 1 in my team fisrt year, -380 elo, National IV next year, +45, -10 this year, i played 2 rounds against >1400 and i didn't sleep because of my baby, so not at my best).

1103 Rapid (with some 1300-1450 perf on tournaments this year, so it's rising usually, certainly +20 next mounth),

1453 Blitz... I think it's my only correct rating, and a but underevaluated because i improved since last year

Thanks! Very interesting article!

Awesome. This should be pinned. I know many people have asked about this over the years. Do you think you'd have time to do one for how the Chess.com ratings correspond to USCF Ratings? 

Great analysis. Was interested and enjoyed this read in 2020! If I understand correctly, chess.com ratings for gameplay are typically lower than FIDE ratings? So if you're 1450 on chess.com you could reasonably expect to be AT LEAST 1450 on FIDE if not 1500/1550+? 

Factoring in over-inflating ratings on self-reporting and so on, it's good to know that it's roughly equivalent. Somewhere around 100 points either way. It gives a good, general understanding (though obviously not precise for those aiming for something more specific for your ratings and so on). You can't obviously expect it to be an exact comparison, but the rough idea of it's nearly equivalent for gameplay with +/-100 points either way is a useful indicator. 

Thanks!
