MMR checker
Riot has never exposed matchmaking rating publicly, so nothing can look it up from a summoner name — including the sites that say they can. What you can do is infer it from the numbers you can see, which is what this does.
ESTIMATED MMR
~1,745
Your badge alone implies about 1,745. The difference comes from your LP gains.
WHAT THAT MEANS
Your MMR and your rank broadly agree. Gains this even mean you are placed about right.
Common questions
Can you look up my MMR from my summoner name?
No, and neither can anyone else. Riot does not expose MMR through its API. Every site that claims to "check" your MMR is estimating it from your rank, LP gains and recent results — exactly what this page does, just without pretending otherwise.
What do my LP gains tell me?
More than your rank does. Gaining over 25 LP a win means your MMR sits above your displayed rank and the system is pulling you up. Under 15 a win with heavy losses means the opposite.
How do I fix bad MMR?
Win consistently, or start fresh. MMR corrects with results, but digging out of a deep hole takes considerably longer than placing accurately on a new account would.
This is an estimate built from community-derived tier boundaries, not a lookup. The LP-gain reading is the reliable part: the gap between what you gain and what you lose is the clearest public signal of where your hidden rating sits relative to your badge.
