This is the perfect size for our food warmers and shallow enough to display more food over a larger area (instead of meat slices, or other foods, being stacked on top of each other, they can now be spread out giving more visual choices to guest) These trays were just Perfect for our needs. Keep in mind that they are a tad thin so the tops don't fit perfectly but that wasn't even the slightest bit of a problem for us. Another little hint: Since these pans are larger, they probably won't fit in your refrigerator like the smaller ones can, so you only can use them On The Party Day. Also, remember to measure your dish washer because they may not fit there either. No complaints for us, they were EXACTLY what we needed.
