Gap 1: Looks Bigger in Photos — Usable Capacity Is Much Smaller

• Gap Type: Size Illusion
• Expectation vs Reality: Buyers expect a 6-quart pot to hold 6 quarts of food. In reality, the usable capacity is often 2/3 of the stated size because you can’t fill a pressure cooker to the brim.
• Frequency: 🔴 Very Common
• Real User Feedback: “The description says it is 6qt. And the pot inside is indeed is 6qt - when filled to the brim!” (3★, helpful=1)
• Why this happens: Manufacturers list total volume, not the maximum safe fill line required for pressure cooking. Photos with wide-angle lenses and no size reference amplify the illusion.
• Buying Tip: Check the inner pot’s usable fill line in reviews or Q&A, and compare the physical dimensions to a pot you already own.
