medium-sized / middle-sized

[riquecohen]

I couldn't find any definite distinction between the two and I see it's not obvious to NESs either. It might well be that it's a matter of collocates. MacMillan and Oxford seem to support what bhai said, that middle-sized is more common in AmE:
Oxford-midsize, MacMillan-middle-sized

Middle-sized can also be shortened to (acc. to those dictionaries): mid-sized, midsized, midsize.

I do not believe that bhaisahab said that middle-sized is more common in AmE; it is not. I have usually heard both medium-sized and mid-sized, but middle-sized only in the context that BobK suggests.

I didn't say that middle-sized is more common in AmE. I said, "I think in BrE it's much more common to say "medium-sized".

Oops. Apologies, a faulty assumption.

Having seen midsize/midsized marked in the dictionary as chiefly North American, I extended it over middle-sized and then over what bhai said, and I ended up with:

'* I think in BrE it's much more common to say medium-sized '(much more common than in AmE),'' while what he was saying was,
'I think in BrE it's much more common to say medium-sized' (rather than middle-sized).

Unfortunately ESL is commercial and largely unregulated. Get monkeys to write tests, pay them peanuts, make more money.

They will almost surely produce a fine test eventually.
