Supermarket Range Size Switzerland 2026: Which Chain Has the Biggest Choice?

On choice, the big retailers lead clearly: Coop offers the widest range across its 982 supermarkets, Migros an average of around 13,000 items per supermarket. Discounters are deliberately leaner, Denner around 3,700 items (75% branded), Aldi and Lidl just a few thousand each. Important: these figures are not directly comparable, because they are measured differently. Content verified: July 2026.

"Who has the biggest choice?" is one of the most common questions, and the answer is clear: the big retailers. But be careful with a direct number comparison, because the chains count their assortment differently.

Why the figures are not directly comparable

The key point: the chains measure "assortment" differently. Coop's 21,600 explicitly refers to the sustainable assortment, not the total of all items. Migros quotes an average per store (around 13,000), depending on the format (M, MM, MMM). Denner's roughly 3,700 is the whole assortment breadth, and the discounter figures for Aldi and Lidl are approximations from comparison reporting (no official Aldi/Lidl assortment figures published for 2025). A straight "21,600 vs 1,300" is therefore misleading.

Discounters carry fewer by design, and that's the point

Aldi and Lidl deliberately run a narrow assortment: fewer items, but larger volumes per item, simpler logistics and lower costs. Anyone after a specific brand or speciality is more likely to find it at Coop or Migros; anyone after a cheap basic shop gets far with the discounter range. A bigger assortment therefore does not automatically mean "better", it depends on what you need.

More choice does not automatically mean more savings. Rappn lists the current promotions of Coop, Migros, Denner, Aldi, Lidl & Co. side by side, neutrally, so you can see what is on promotion where this week for your own shop.
