Many players are curious about how the different chess.com ratings stack up against each other.  This survey is designed to figure out the answer!  

At the bottom of the survey there are also a few questions about USCF and FIDE ratings for comparison purposes.  If you would like to remain anonymous on chess.com it's recommended you leave the USCF/FIDE fields blank.

To help keep the survey accurate please only fill in fields when you have 25+ total games in that category, and 5+ games in the last 6 months.  As the results start to come in I'll create a few plots and summary tables in the results spreadsheet.  Enjoy!

    Oldchessdog, I think you did something wrong with your math. If your online (turn-based) rating is 1792, you can expect your USCF rating to be ~1760, +/-200 or so.

    Your blitz rating of 1109, which has been shown elsewhere to be generally a more reliable measure, would suggest you'd be ~1240 USCF.

    If this is true, than my USCF rating is now closer to 1750!??

    Well, it's a nice dream. Time will tell. I'll start playing in tournaments again when I get back to Texas in February.

    Actually those graphs imply very strongly that at blitz, something other than chess ability is highly influential to the point of possibly being the most defining factor.

    website sucks! very good competition. the problem is with timer. they have no control over the lagging from player to player. quite obvious either you pay or you are punished. play for free means you lose

    Is there any possibility that the standard ratings will be properly adjusted?

    Can anybody explain why my rating jumps around so massively. In one game, I'm 1200, in the next game down to 1036.

    Thanks for publishing these results! Lots of scatter, but that was to be expected.

    Very useful, interesting, and original to put this together.  Thanks.

    ratings on chess organizations rate differently, your ratings are higher or lower depending on the club you play. if you play a sactioned fide tournament they will rate you accordingly.

    Yijiqishi, I was typing on my phone and it auto-corrected the word I typed. I meant "turn-based". On this site, that is the same as "correspondence chess". But I'm guessing you knew that because the context was clear.

    I'm very interested in this, but I'm colorblind, so that graph is very difficult to read :( So many shades of blue.

    Thank you for doing this work! 

    If you were to make a similar graph using the same data, but "Turned Based" as the measuring stick rather than "blitz", I am pretty sure you would get a very different picture. What was your lower limit on games played in correspondence chess ("turn based") to figure out whether a rating had stabilized?

    Do you know if theres any way to use an engine to determine what rating on chess.com standard corresponds to a rating of 2000 fide/uscf?

    You should really request that people submit their USCF member ID. After conducting my own survey, in which I did so, I found the vast majority of people are not entirely correct about their USCF rating. For example, one guy was convinced he had a standard rating, even though he only had a provisional 'quick' rating.

    Furthermore, five games in the past 6 months is not active. Someone who played five games USCF a half year ago, but plays and studies everyday on chess.com, is not going to have an accurate USCF rating. In my own survey, I only included people who were playing 1 or more tournaments per week. In that case, the difference between chess.com blitz and USCF standard was double what you see here.

    Updated the table and added a plot at 265 responses.  Some outliers were fixed/removed.

    I thought that USCF was more inflated... no?

    Another plot with the standard ratings only. It appears that a Chess.com player progression is "slower" than the FIDE player progression! On the other hand, the chess.com players start "over-rated"...
