What does each spice level mean?

smutrecs.com rates spice from 0 to 5 by how much sex is on the page and how detailed it is: 0 means none, and 5 means explicit and frequent, central to the book.

LevelLabelMeaning
0NoneNo sex on the page; kissing at most.
1Closed doorClosed door or fade to black.
2MildSome sensual detail; scenes mostly off the page.
3ModerateOpen door; a few scenes with moderate detail.
4HighOpen door; several detailed scenes.
5ExplicitExplicit and frequent; central to the book.

The scale measures only how much is on the page and how often. Themes are rated separately as darkness, and topics such as violence or grief are listed as content warnings. When the evidence falls between two levels, we use the lower one.

How we rate explains where the evidence comes from and when a rating is marked as checked.
