They’re related, but not always the same.

• Sheet pan: Usually a rimmed rectangular pan (often called a half, quarter, or jelly roll pan). The rim helps contain oils and juices, so it’s handy for roasting veggies or sheet‑pan dinners.
• Baking sheet: Often used to describe a rimless cookie sheet. The open sides make it easier to slide off cookies, but it’s not ideal for anything that could leak.

On Walmart’s sheet pan page, you’ll see mostly rimmed pans in different sizes and materials (aluminum, carbon steel, stainless, nonstick) that work for baking and roasting. Always check the product details for style and dimensions.

It depends on how you bake and clean up.

• Aluminum (bare): Heats quickly and promotes even browning. May discolor in the dishwasher; hand-washing can help appearance.
• Stainless steel: Durable and often dishwasher-friendly. It can heat a bit slower but resists rust.
• Carbon steel: Sturdy and responsive. Some versions have nonstick coatings; care needs vary.
• Nonstick coatings: Easy release and cleanup. Typically suited to moderate temps; check the max oven temperature in the listing.
• Thicker gauge or textured pans: Can help with even baking and reduce warping.

For everyday use, a rimmed half sheet in your preferred material can be a versatile pick.

You’ll see several common sizes on the page:

• Half sheet: About 18" x 13" (fits many home ovens). Everyday go-to for cookies and roasting.
• Quarter sheet: About 13" x 9" or 13" x 10"; handy for smaller batches.
• Eighth sheet: About 10" x 7"; great for toaster ovens or prep tasks.
• Jelly roll: Around 15" x 10" with rims; popular for rolled cakes and bars.
• Extra large: Some home ovens can accommodate pans near 21" x 15"; always measure first.

Names can vary slightly by brand, so rely on the listed dimensions when choosing.

A quick measurement helps avoid returns.

1. Measure your oven’s interior width and depth between the rack guides; leave clearance for air flow.
2. Compare to pan dimensions listed on the product page. Remember the rim adds width.
3. Common fit: Many standard ovens accept an 18" x 13" half sheet. Narrow or compact ovens may need quarter or eighth sheets.
4. Toaster ovens: Often use quarter or eighth sheets; check your appliance manual.

If you’re unsure, filter by size on Walmart.com and review the dimensions in the specs. Choosing a pan slightly smaller than your maximum interior space can make sliding it in and out easier.

Care needs vary by material, so check your product’s instructions.

• Cool before washing: Let the pan cool to reduce thermal shock and potential warping.
• Nonstick: Use soft sponges and mild detergents; avoid metal utensils and abrasive pads.
• Aluminum (bare): Hand-washing can help maintain appearance; dishwasher use may cause discoloration.
• Stainless steel: Often dishwasher-safe; for stuck-on bits, try a warm soak or a baking-soda paste.
• General tips: Avoid harsh scouring, dry thoroughly to reduce rust on steel, and store pans flat. For high-heat or broiler use, verify the pan’s max temperature on the listing.
