Crimson Hanging Sign is the nether wood variant of the hanging sign family — a text block that hangs underneath blocks or from its own solid bracket instead of standing on a post. One recipe turns 6 stripped crimson stems and 2 iron chains into 6 Crimson Hanging Signs on a crafting table. A placed Crimson Hanging Sign holds up to four lines of text, and the lines run narrower than on a regular sign, so long words need planning. Crimson Hanging Sign stacks to 16, breaks with any tool — an axe works fastest — and became available in the base game with Minecraft 1.20 on both Java and Bedrock.

Players hang Crimson Hanging Sign in three ways: on the side of a block for a solid self-supporting bracket, under the bottom of a block for parallel chains, or beneath a narrow block such as an iron chain, where both chains meet in an up-arrow shape. Interacting with a placed Crimson Hanging Sign opens the text editor; dye recolors the text, a glow ink sac makes the text glow, and a honeycomb waxes the sign permanently against edits. Water flows around Crimson Hanging Sign without destroying it, and the crimson variant cannot serve as furnace fuel — overworld hanging signs smelt 4 items each, while nether wood signs smelt none. The bracket of a Crimson Hanging Sign is solid with collision, while the sign board itself has no collision.
