Retail’s European calendar is thin but each fixture is enormous. IFA Berlin, though a consumer electronics show at heart, dwarfs every other event tracked on Sesamers by attendance. Ranked by verified attendance.
1Rank
Retail tech, building automation, HVAC 4-8 Sep 2026, Messe Berlin 220,000 attendees
The world's largest consumer electronics and home appliance show, with a significant retail technology and checkout hall alongside its consumer-electronics core. By far the largest attendance of any event tracked on Sesamers, in any vertical.
Why it is hereThe single largest audience Sesamers tracks anywhere – though the core crowd is consumer electronics buyers, not retail-tech specialists.
2Rank
Checkout and returns, marketplaces, retail tech 30 Nov-1 Dec 2026, Paris Expo Porte de Versailles, Hall 7.2 15,000 attendees
Easyfairs' dedicated retail technology tradeshow in Paris, with a full checkout, returns and marketplace-infrastructure programme. The specialist retail-tech event on this desk, unlike IFA's broader consumer-electronics focus.
Why it is hereThe purpose-built retail-tech show – smaller than IFA but the room is entirely retail buyers, not appliance shoppers.
3Rank
Checkout and returns, marketplaces, retail tech 15-17 Sep 2026, Paris Expo Porte de Versailles 12,500 attendees
The European edition of the US National Retail Federation's flagship show, bringing its retail-innovation programming to Paris. Runs the same week as IFA Berlin.
Why it is hereThe NRF name brings a different, more US-influenced retail buyer than Tech For Retail's continental European crowd – useful if you sell on both sides of the Atlantic.
Attendance figures come from each event’s own record and organiser statements. NRF Retail’s Big Show Europe and IFA Berlin run within three weeks of each other in September – plan travel accordingly. Only three events carry the retail and e-commerce tag; this is a thinner calendar than fintech or cleantech, and sourcing more regional retail-tech events is a priority.
Common questions
Which is the largest retail event in Europe?
IFA Berlin at 220,000 attendees – though it is primarily a consumer electronics and appliance show with a retail-tech hall, not a dedicated retail conference.
Which event is purpose-built for retail technology?
Tech For Retail in Paris, at 15,000 attendees, run by Easyfairs with a full checkout, returns and marketplace programme.
Why are there only three retail events tracked?
The vertical's event calendar on Sesamers is thinner than fintech or cleantech – a known gap. Regional retail-tech events across Europe are a sourcing priority.
Does Sesamers take payment for placement on this list?
No. Rankings are by verified attendance. Events are listed because they are tracked in the Sesamers database, not because they paid.
