The Winco Silicone Baking Mats come in two different sizes:

• Half size: The half size mat measures 16-1/2" x 8-5/8", and is designed to fit perfectly into a half-size sheet pan. This size is ideal for baking cookies, biscuits, or other small to medium-sized baked goods.

• Quarter size: The quarter size mat measures 11-7/8" x 8-1/4", and is designed to fit perfectly into a quarter-size sheet pan. This size is ideal for baking small batches of cookies, pastries, or other small baked goods.

Both of these baking mats are made of high-quality silicone, which is a non-stick and non-toxic material that is safe for use in the oven. The mats are flexible and durable, and can be reused many times. They are also easy to clean, and can be washed by hand or in the dishwasher.

The Winco Silicone Baking Mats are perfect for use in both home kitchens and commercial bakeries. They are a great alternative to traditional parchment paper or cooking spray, as they are reusable and more environmentally friendly. Overall, these baking mats are a versatile and useful addition to any kitchen.
