Which LEGO Set Was That?

Describe a set you remember in your own words, add the theme and decade if you know them, and pick it from the pictures. It is free and needs no account.

Name what was in the box: the building or vehicle, the characters, the creatures. A decade in your words, like “the 90s”, counts too. Try an example.

How to find a LEGO set you remember

  1. Name what was in the box. The building or vehicle (castle, pirate ship, fire station), the characters (a wizard, Darth Maul) and the creatures (a dragon, horses). Those are the words set names and their figures use.
  2. Add the theme if you know it. Castle, Star Wars, Friends, Technic: the theme cuts the catalog the most.
  3. Add the decade. Choose it, or say it in your words: “from the 90s”, “around 2010”.
  4. Pick yours from the pictures. The page shows up to 24 sets, best match first, then the biggest sets your choices leave. If you know the number, type it and that set comes first.

How accurate is it?

We chose 35 sets at random from the catalog’s sets of 60 to 3,000 pieces released 1980 to 2025, leaving out gear, books and Duplo, described each from its picture without reading its name, then searched all 20,280 sets for it. Measured November 03, 2026. Many of the sets were recognisable from their pictures, so their descriptions use words from the set’s name; a vaguer memory will rank lower. With this few sets, take the counts as a rough guide.

What it cannot do

It reads each set’s name, its theme and the names of the figures it came with, so a set named for a place or a story, with no figures, is found only through the theme and decade. It does not look at photos. If you have the pieces, What Set Is This From? works from them instead. The tool itself saves nothing, but your description travels in the page’s address, which the site’s analytics note as they do for any page.
