Do Ikea quilt covers fit other standard sized duvets/quilts other than Ikea brand quilt?

I mean, if I have a standard American full/queen quilt/duvet that I bought somewhere other than IKEA and I purchase an IKEA full/queen quilt cover, will it fit my non-IKEA quilt or duvet? I’m having some trouble getting my plain (not super fluffy or anything) duvet into the IKEA cover. I usually have a little trouble with duvets and their covers no matter where I purchased them, but I was wondering if Ikea quilt covers are only compatible with Ikea quilts. Thank you.

Yes it should fit, they use to have different sizes …I guess Europeen sizes vs American ones…but that was maybe 15 years ago…well when I was a teenager it use to be like that and I’m 31 now…so, it’s been a little while.
Be sure that full is full and queen is queen…I think for IKEA full is like Double and after it’s Queen and then King…maybe you are trying to fit a queen in a full and that won’t work…
