How cookware choices are made
Where the catalog’s figures come from, how the tools use them, and what they can’t tell you.
On this page
Every figure comes from the maker
We take each pan’s contents, material, care and stove facts from its maker: the product page, the current manual or the spec sheet. Where the maker leaves a gap, an authorized retailer’s page for the exact same model may fill it. What a maker says about a whole line isn’t copied onto every product in it, and a figure nobody publishes stays blank.
How the gap finder orders sets
The gap finder starts from four everyday pans, which you can change: a skillet, a saucepan, a sauté pan or braiser, and a big stockpot or Dutch oven. It first keeps only cookware whose maker says it suits your stove and the care you asked for. Sets that fill more of your missing pans come first, then those that repeat fewer of the pans you already own. After that, a set ranks higher when it covers more of the four everyday pans, then more cooking jobs in all, counting the optional ones such as a wok or a steamer, then when it holds more pans, then more lids; only then does it go by brand and name. Price, commission, which shops we link to and popularity play no part.
What the specs can’t tell you
A spec sheet can’t tell you how evenly a pan heats, how long it lasts, how the handle feels or how well food releases. We haven’t cooked with these pans and don’t claim to have. A pan and its lid can have different oven limits; use the lower one. Your stove’s manual has the last word on what fits it.
Changes and corrections
Each product keeps a source for every figure. If a source page disappears, the product stays and so do its figures. Tell us on the contact page when a figure looks wrong; we change a stove or care fact only after checking the maker’s own page.
What this site compares
This catalog compares US cookware sets and single pots and pans by what’s actually in the box, the cooking jobs each piece does, the stoves its maker says it works on, and its care. It doesn’t rank how well pans cook, and it doesn’t give health advice about coatings.
Pans first, then everything else
Each set’s pots and pans are counted apart from its lids, inserts, utensils, pan protectors and storage pieces. A lid that fits two pans counts once. A lid that doubles as a skillet keeps both jobs on its product page but counts once in the box. A saucier does a saucepan’s job; a grill pan doesn’t replace a flat skillet.
Specifications don’t expire
A maker’s specification for a model doesn’t change once the model exists, so each product links to its source and carries no review date or expiry. Age never takes a product out of the finder; only a product marked as no longer current is left out of suggestions. We don’t track stock or prices.
Sizing guidance and household lists
Household lists use different rules from our serving guide. For two: an 8–10-inch skillet plus a 1–2-quart saucepan, using Made In’s small-meal size bands. For four: a skillet at least 12 inches across, including frying-only bundles; Made In’s 12-inch example fits four eggs or three chicken breasts, not four portions of every meal. For five-plus: the four core shapes and a large pot of at least 6 quarts, applying Lodge’s quart-per-person crowd guidance to a six-person example. These are our selection rules, not maker guarantees about household size.
The serving calculation divides the chosen volume by a liquid portion. Its fill percentage is an editable example, not a safe operating limit. Round cooking-surface area is π × diameter squared ÷ four. Neither calculation predicts heating, food release or portions of solid food.
Kitchen conversion method
The grams-to-cups tool uses household portion weights from USDA FoodData Central’s SR Legacy release. We divide grams by the selected ingredient’s grams per cup, or multiply cups by that weight for the reverse conversion. These are reference portions, not measurements of your particular batch.
We preserve packed and unpacked brown sugar, sifted and unsifted powdered sugar, raw and cooked rice, and fluid rather than whipped cream. “One cup, dry, yields” would describe a cooked yield, so it is not used as a dry ingredient’s cup weight. Drinking water uses the published serving of eight US fluid ounces, equal to one US cup.
The kitchen-unit converter uses US customary measures. NIST defines a US gallon as 231 cubic inches, an inch as 2.54 centimeters, a gallon as 128 fluid ounces, and a cup as eight fluid ounces. That gives 236.59 mL per US cup by arithmetic. One cup is 16 US tablespoons or 48 US teaspoons. An ounce by weight is 28.349523125 grams.
The spoon and milliliter pages use the same USDA cup weights, divided by the size of the measure: a US tablespoon is 1/16 cup, a teaspoon 1/48 cup and a milliliter 1/236.59 cup. Every spoon figure is worked out from that one cup weight, so a cup, its spoons and its milliliters always agree. Each answer is also written as level US cups and spoons to the nearest 1/8 teaspoon, rounded further from a quarter cup up, as the recipe scaler does.
The calculator rounds only the answer shown on screen, not the arithmetic between steps. An exact common fraction may accompany a decimal; other decimals are rounded for display. Ingredient results always say “about,” because filling, packing and the ingredient can change a cup’s weight. A rounded value is not a promise of a perfect baking result. When a recipe gives a gram weight, use that weight.
The amounts you enter are not saved or added to the page address. Switch between grams and cups after a valid answer and the converted amount becomes the new starting amount. If the amount is invalid, the old answer disappears. To turn weight into volume, follow the link to choose an ingredient; flour and sugar need different cup weights.
The recipe scaler divides the servings you want by the servings the recipe makes and multiplies each line’s leading amount by that factor, as an exact fraction. Only the amount changes; the unit and the rest of the line stay as typed. An awkward cup or spoon result is then written as measures from a standard US set, so 1/6 cup reads 2 tablespoons and 2 teaspoons; from 1/4 cup it rounds to the teaspoon and from 2 cups to the tablespoon, and says “about” when it rounds. A line it can’t read safely, such as a range, a can size, a step or “to taste”, stays as written with the reason. The list stays in your browser tab and is never sent or saved.
