How should we record the dimensions of a rhombus coin? For a rectangle, we record the length of the longer side and the length of the shorter side. For a rhombus, the four sides usually have the same length. The current guidelines suggest that we should record the length of the longer diagonal. Should we change that and record the length of both diagonals?
Most coins currently described as “rhombus” are actually squares having a design aligned with the diagonals. Before changing anything about how to record the dimensions of rhombus coins, we should probably settle the debate of square vs. rhombus (https://en.numista.com/forum/topic122825.html).
So you mean we should record size of the sides of rhombus? In that case, most rhombuses (diamonds) will actually have the same size for the side a and the side b. Not mentioning that the round corners can make it difficult to measure the sides.
That's why I was asking whether, unlike rectangles, rhombuses should be recorded with the size of the diagonals. I believe it would be easier to measure accurately this way and it is more representative of the size of the item.
That makes sense, too. The problem I see is the large majority of the rhombuses in Numista are also squares. Do we want different measurements for squares just because they are rotated 45 degrees?

Definitely not! I'll revive that other discussion about rotated squares.
