A well-fitting pot lid helps retain heat and moisture while cooking and can reduce splashes around the hob. When choosing a replacement or extra lid, start with compatibility: check the diameter and shape of your pot and compare them with the specifications of the lid. The rim and overall design also need to suit the cookware for the lid to sit securely.
Pot lids are usually matched to cookware by diameter, but the stated dimensions alone may not guarantee a perfect fit. Differences in rim design can affect how a lid sits on a particular pot. If you are replacing a lost or damaged lid, checking the measurements and specifications of both pieces is therefore important.
If you are replacing more than the lid or putting together your cookware, see our pots and broader collection of pots and pans.
Covering a pot reduces the amount of steam and heat that escapes, making a lid useful when bringing liquids to the boil, simmering food or keeping cooked dishes warm for a short time. Whether a pot should stay covered throughout cooking depends on the recipe: leaving the lid off allows more moisture to evaporate, while covering the pot helps retain it.
Only if it is compatible with your pot. Matching the diameter is important, but the shape and rim design also affect whether the lid sits securely, so compare the specifications of both pieces before choosing.
Check the diameter where the lid is designed to sit and compare it with the lid specifications. Also consider the shape and rim design, as the same stated diameter does not always guarantee the same fit.
