Proposers often ask how many partners a typical RIA or Innovation Action needs. Pick an action type for an immediate curated range, then optionally paste a call code to see medians from historical funded projects on GRANTIBASE. Results are indicative — not official Commission advice.
Consortium size calculator
Indicative consortium size ranges for Horizon Europe action types — with optional enrichment from funded CORDIS projects when you paste a call identifier.
Typical consortium size
Usually 8–15 partners
Common range: 5–18
Collaborative Horizon Europe RIA projects typically land in the mid-teens for partners, with a common band around 5–18.
- Eligibility note
- Collaborative RIA topics usually require a consortium of at least three independent legal entities from three different EU Member States or Associated Countries — always confirm the specific topic text.
- Typical coordinator
- Often a university, research organisation, or experienced R&I coordinator with strong scientific leadership.
Larger consortia when
- Multi-domain / multi-cluster topics needing coverage across disciplines
- Large demonstration or data-collection work packages
- Need for broad geographic and stakeholder representation
Smaller consortia when
- Focused scientific questions with a tight work plan
- Topics that emphasise excellence over breadth
- Limited budget that cannot support a large partner list
Indicative guidance based on typical Horizon Europe patterns — not official Commission advice. Always read the specific call conditions.
