The quick answer
For most kitchens, start with 13-gallon drawstring bags. For garage cleanup, yard waste, or heavy meat trays, move up to contractor bags instead of trying to make kitchen bags do heavy work.
What to compare before buying
Size: 13 gallon is the standard kitchen can size. Tall kitchen cans usually need drawstring bags.
Count: Big boxes usually win if the price per bag is lower and you have storage space.
Thickness: Heavy-duty bags are worth it when leaks cost more than the small savings.
Scent: Skip scented bags if anyone in the house gets headaches or has sensitive skin.
Use case: Kitchen, bathroom, outdoor, contractor, and yard bags are different products.
