square tin pan

Common materials include aluminum, steel (including carbon steel), and foil.

Square cake pans most commonly come in 8‑inch and 9‑inch sizes. Depths are typically around 2 to 2.5 inches (examples from listings: 2" H × 9" W × 9" D; 2.5" H × 9" W × 9.7" D; 2.2" H × 8.6" W × 8.6" D).

Available finishes include coated nonstick surfaces (such as silicone-style or reinforced nonstick coatings) and uncoated natural aluminum, which some listings describe as naturally nonstick. Some product descriptions also note coatings made without PFAS or PTFE.

Some square pans include a plastic or snap‑on storage lid; listings that include a cover will often state “Includes: Lid.” Verify the product description if a lid or cover is important to you.

Look for reinforced or encapsulated steel rims and descriptions that advertise warp‑resistant or reinforced construction—these features help keep the pan rigid and flat under heat and heavy use.

Square springform pans use a removable band with a buckle or locking latch that secures the sides to the base; when released, the band opens so the dessert can be lifted free. Some listings note the base can double as a serving tray.
