Question re: the small bag on FR.
Officially, the small bag allowance is 40 cm x 20 cm x 25 cm. Back when FR introduced this, they claimed their sizers were up to 25% larger than this, effectively allowing you to take an item of up to 42 cm × 30 cm × 20 cm.
Is that rule still in effect? IIRC, the fact that the sizers are bigger was even to be found in FR's ToS. But it's def not in them anymore, just checked.
