Fence

A fence is a barrier block that cannot normally be jumped over, similar to a wall. Unlike a wall, a player (but not mobs) can see through the openings in a fence.

All types of fences can be obtained through crafting.

While fences appear to be a single block tall and have a hitbox height of one block, their collision box (for entities) is 1.5 blocks tall, meaning most mobs cannot jump over them without the Jump Boost status effect. They are transparent to light and have visual gaps in the model. Spiders can climb over a fence, just like any other vertical object. Camels can walk over fences.
