- "These straightforward but surprisingly dangerous charms cause certain things to swell or shrink. You will be learning both charms together, so that you can always undo an over-enthusiastic cast. There is thus no excuse for having accidentally shrunk your homework down to microscopic size or for allowing a giant toad to rampage through your school’s flower gardens."
- —Miranda Goshawk[src]
The Shrinking Charm (Reducio) is a charm that causes an object to shrink. It is the counter-charm to the Engorgement Charm, causing enlarged objects to return to their original size. The Shrinking Charm is also used as the potion-making spell for the Shrinking Solution.
The use of a Shrinking Charm on a human is considered both complicated and dangerous.

Behind the scenes
- In Harry Potter and the Deathly Hallows: Part 1 the scene in which the spider is enlarged is replaced by a mirror scene including Bluebell Flames.
- The effects of this charm bear great similarity to those induced by the incantation of Diminuendo, used by Nigel Wolpert in 1995.
