My mind is blown. How did I not know that there is no standard sizing.
I have either been living under a rock (possible) or have been gaslit by the bedding and manchester (Aussie term) industry for 50+ years.
I get UK sizes may vary with AU sizes, but I did not know that IKEAS are one size and in department stores (it is completely pot luck).
Every year, we have an existential bedding crisis at the great summer/winter doona/duvet swap out. The covers don't fit.
So this year I measured them and realised the rookie error I have made.
Mind is quite warped by this discovery. Am I. The only person on the planet who didn't know this???
YABU - Def living under a rock
YANBU - agree that mismatched size standards are batshit.
