The calculator covers the rank restrictions from Iron to Challenger and displays the result in a simple list. It also helps separate Solo/Duo rules from the more flexible Flex queue rules.

LoL Duo Rank Calculator 2025

League of Legends Solo/Duo queue does not allow every rank combination. The allowed range depends on your current tier and, in some cases, your division. This can make it difficult to know whether two friends can enter the same ranked queue.

Use the calculator above to select one rank. It will show the ranks that can legally duo with it under the 2025 rules used by this page. You do not need to compare the full ladder by hand.

How to Check Duo Queue Eligibility

1. Open the rank selector.
2. Choose your current Solo/Duo rank.
3. Review the displayed allowed ranks.
4. Copy the result list if you want to send it to a teammate.

The result is a quick compatibility check. It does not change your rank, place you in a queue, or predict the result of a match.

Solo/Duo Rank Restrictions

Solo/Duo restrictions are designed to keep large skill gaps out of the same ranked party. The permitted range is broader in the lower tiers and becomes stricter as players move higher on the ladder.

Iron, Bronze, and Silver players generally have more room to duo across nearby tiers. Gold and Platinum use a narrower range. Emerald and Diamond use more detailed division-based rules, so the exact selected division matters. At the top of the ladder, Master, Grandmaster, and Challenger have the strictest limits, and some combinations are not available for duo queue.

Because the rules are not identical for every tier, checking the selected rank is more reliable than using a simple “one tier apart” assumption.

Why Rank and Division Matter

A tier alone may not always give the complete answer. Diamond and Emerald combinations can depend on the division shown in the calculator. This is why the tool lists individual ranks instead of only showing broad tier names.

If a possible partner does not appear in the result, that combination is not available for the selected rank. You can try another eligible rank or use a different queue when you want to play with a wider group of friends.

Solo/Duo and Flex Queue Are Different

This calculator is focused on Solo/Duo compatibility. Flex queue follows different party restrictions and is generally more flexible for players who want to queue across a wider rank range.

For Flex, the rules shown in the reference for this calculator allow broader combinations below the highest tiers. Master-level and higher Flex groups still have minimum-rank requirements. Do not use a Flex assumption to predict Solo/Duo eligibility; select the correct queue before making plans.

Common Duo Queue Problems

• A friend has a different tier or division.
• The party looks valid but the queue rejects it.
• An old rank chart no longer matches the current rules.
• Players confuse Flex restrictions with Solo/Duo restrictions.
• A high-rank account has fewer available duo partners.

The calculator is useful before a ranked session because it checks the selected rank against the displayed compatibility list in one step.

LoL Duo Rank Calculator FAQ

Can I check who I can duo with?

Yes. Select your current Solo/Duo rank and the calculator will display the ranks that can queue with you.

Does the calculator cover all ranks?

It covers the ranked ladder from Iron through Challenger, including divisions where the rule requires a more detailed check.

Does this calculator work for Flex queue?

The main result is for Solo/Duo. Flex queue uses separate rules, so its party limits should be checked independently.

Why is my friend’s rank not listed?

The selected rank and your friend’s rank may not be compatible under the displayed Solo/Duo rules. Check the exact division and make sure you selected the correct queue.

Are these rules permanent?

Ranked queue rules can change. This page is labeled for 2025, so check the current in-game information if Riot updates the restrictions.
