Solid Block is the term for a block that has a collision box that a player, mob, or entity cannot pass through. Most blocks are solid, while most plant types are not. Ladders are treated as solid as it is possible to stand atop them without descending. Both water and lava are not solid and can be passed through.
Most solid blocks are 1 meter high, but certain blocks have non-standard heights in comparison. Below is a list of blocks with non-standard height.
