Open door or closed door and how to read heat levels in romance

Romance novels are not all alike in how much they show. Readers use a few simple words to tell them apart, and knowing them saves you from a surprise. This guide explains the terms you will see most often.

Closed door

In a closed door romance, intimate scenes happen off the page. The door closes and the next chapter begins. These books are often called sweet or clean romance. They can be full of longing and tension. They simply leave the bedroom to your imagination.

Open door

In an open door romance, the reader stays in the room. Scenes are explicit, and the book is written for adults. You will also see the words steamy or spicy used for these books.

Slow burn

Slow burn is about timing. The couple takes a long while to get together. A slow burn can be open door or closed door, so the two labels answer different questions. One tells you how long you will wait, the other tells you what you will read when the wait is over.

Content notes

Many romance novels also carry content notes. These list difficult subjects that come up in the story, such as grief or illness. They are there so that you can decide whether a book is right for you today. A content note is information. It says nothing about how good the book is.

Why labels help everyone

A reader who wanted a sweet story and got an explicit one feels misled, and the same is true the other way round. Clear labels mean the right readers find the right books, and nobody leaves a bad review because of a mismatch.

Other words you will meet

Clean romance and sweet romance usually mean closed door, with little or no strong language. Steamy and spicy mean open door. Fade to black is another way of saying closed door, because the scene ends as the lights go down.

Some readers use a scale of chilli peppers or flames to rate how explicit a book is. There is no official scale, so one reviewer’s three may be another’s five. The description written by the publisher is the most reliable guide.

Choosing for someone else

If you are buying a romance as a gift, the heat level matters even more. A cosy story is a safe choice for most readers. For an open door book, it is worth knowing the person’s taste first.
