The smallest box that fits with XLOOKUP
PremiumIn C2, pick the smallest box that holds the volume in B2. If there is no exact match, XLOOKUP should take the next larger size: match_mode 1, the fifth argument, XLOOKUP(B2,$E$2:$E$5,$F$2:$F$5,,1).

Why this works
match_mode 1 means "exact match, or else the next larger value". There's no 12-liter box, so XLOOKUP takes the next size up, 20 liters, the Large box. Filled down, 4 liters gets Small, 27 Extra large and 20, an exact match, Large too.
Common mistake: Using -1, the next smaller value. For sizes and capacities that picks a box that is too small.
The answer
- C2
=XLOOKUP(1B2,2$E$2:$E$5,3$F$2:$F$5,,51)
In plain words: Find 1the volume in B2 in 2the sizes in E2:E5 and return 3the box from F2:F5, 5taking the next larger size when there is no exact match.
