I understand that this fixed the author's issue, so if it works for them it works for them. But, it also assumes only 5 common can types and a lot of wall space. The latter is the real killer for a small house as wall space is at a huge premium, being the only place you can put cupboards (even when the room sizes are large enough to support islands, walls are still the only real place for tall things). If I had a square metre of wall to devote and did this, I'd subdivide this horizontally and have, say, 15 short columns in 3 rows rather than 5 long ones. If I really have so many of a specific type of can in stock that they don't fit, they can have two columns.
