inner width
inner height
inner depth
inner breadth

the 'inner' anything should be enough to understand what is being referred to.

since inner and any term referring to space or volume, or whatever, can be freely put together and taken apart, and since I assume the same for the German, I see no reason for LEO to include all such possible pairs.

lichte Weite - clear width
lichte Breite - clear width
lichte Tiefe - clear depth (not entirely sure though )
lichte Höhe - headroom , headway

Thank you!
