Your purchase notes
Keep the details in one place.
Choose the capacities and diameters you use, then check the material and hob compatibility. A set is useful only if its sizes are useful.
Keep capacity and diameter beside each other. Where the seller specifies whether a diameter refers to the rim or base, retain that distinction.
Compare the cost per unit
Choose one consistent unit: pieces, kilograms, litres or prepared litres, as appropriate. Divide total cost by the quantity. Do not compare unlike product types on price alone.
