# Wikidata:Property proposal/horizontal depth

### horizontal depth

Originally proposed at Wikidata:Property proposal/Creative work

Description Spatial extent for 3D object along the third axis, what is most commonly referred to as its depth. depth (Q3250078) Quantity "depth" in c:Template:Size --> Any object with spatial extent All positive one-dimensional values with a length unit same as height (P2048), width (P2049) The Thinker (Q18003128) → 148 cm The Kiss (Q2418237) → 117 cm Flamingo (Q3073296) → 63.5 ft I was planning on looking into sculptures with height (P2048), width (P2049) and thickness (P2610) and converting some thickness (P2610) to depths vertical depth (P4511), thickness (P2610), height (P2048), width (P2049)

#### Motivation

At the moment per Wikidata:WikiProject_Visual_arts/Item_structure#Dimensions refers to 3 dimentions of sculptures as height (P2048), width (P2049) and thickness (P2610). However when we discuss "thickness" of 3D objects it is usually not in context of the horizontal depth. For example thickness of bronze statues, we usually refer to the wall thickness, (see [1] or [2]). Same with pottery (see here), Alexander Calder (Q151580) sculptures (see here), etc. There are cases where people refer to depth / thickness of an 3D object interchengbly, but it is rare. That is why I would want to differentiate thickness of the object from horizontal depth. Also templates like c:Template:Size were always differentiating them and the mixing of those two terms makes it problematic when fetching data from Wikidata, as you do not know which one it is. So thickness (P2610) of Flamingo (Q3073296) should be 3/4 inch and horizontal depth 63.5 ft. Jarekt (talk) 12:48, 11 July 2018 (UTC)

#### Discussion

•   Support Yes, I remember there was considerable confusion about this when depth was being discussed, I agree we need this as a separate property. ArthurPSmith (talk) 17:37, 11 July 2018 (UTC)

•   Support If we approve this proposal, please, review and make good definitions and examples on the rest of dimmensional properties P2610, P4511, P2048, P2049, to avoid (more) missunderstandings. Good proposal. Thanks Amadalvarez (talk) 10:53, 18 July 2018 (UTC)
Will do. --Jarekt (talk) 02:02, 20 July 2018 (UTC)

Thank you. I am traveling at the moment but can look into this in a couple weeks. --Jarekt (talk) 17:22, 25 July 2018 (UTC)
