What capacity should a kitchen scale have?

Most cooking and baking reviewers converge on 11 lb (5 kg) as a comfortable everyday minimum. Sourdough bakers, batch cookers, and anyone weighing whole stockpots tend to recommend 22 lb (10 kg) or higher. Pure precision pocket scales typically top out around 1 kg, which is why they're a complement to, not a replacement for, a kitchen scale.
