The best grill mat for your outdoor grill depends on where you want it to go. Thin, nonstick mats sit on the cooking grates to help keep small foods from falling through and make cleanup easier. Larger protective mats go under the grill to catch grease and spills on a deck or patio. These products serve different purposes, so this guide compares both types and explains which one may fit your setup.
For cooking on the grates, the GRILLART set stands out for its stated heat resistance, while the RENOOK and WIBIMEN sets offer several reusable mats. If your main concern is protecting the ground below your grill, consider the Linda’s Essentials or UBeesize mat instead. Always check the product’s heat limits and use instructions before grilling.

RENOOK Grill Mat Set of 6: A Versatile Set for Regular Grilling
The RENOOK set includes six nonstick mats, each measuring 15.75 by 13 inches. They are designed to sit on cooking grates and help keep small pieces of food from slipping through. The mats are listed for use with gas, charcoal, and electric grills, and the product description also mentions roasting and baking.
Heat limits are important with this set. RENOOK specifies a maximum of 400°F for short use and 260°F when the mat is used for more than 30 minutes. That makes it important to avoid treating this as a high-heat, leave-it-on-the-grill accessory. Follow the product instructions and keep it away from direct contact with flames or hot coals.
Six mats offer flexibility: use several at once, keep spares on hand, or trim a mat to suit a pan or cooking area. The description says they can be washed on the top rack of a dishwasher. Cutting them may be useful for fit, but do so only if you are comfortable altering the mat and can keep the cut edges away from unsafe use.
Pros:
- Six mats provide multiple pieces for cooking or backup.
- Nonstick surface helps keep smaller foods on the cooking area.
- Listed as suitable for gas, charcoal, and electric grills.
- Top-rack dishwasher safe, according to the product description.
Cons:
- Its stated heat limit is lower than the GRILLART and WIBIMEN mats.
- The lower limit for longer use calls for careful temperature management.
Verdict: Choose the RENOOK set if you want several reusable cooking mats and can grill within its clearly stated heat limits.
Linda’s Essentials Under Grill Mat: Compact Coverage for Decks and Patios
This 48-by-30-inch mat is designed to go beneath an outdoor grill, not on the cooking grates. Its purpose is to catch grease, oil, and spills that might otherwise land on a deck, patio, or lawn. The double-sided silicone coating and stitched edges are intended to make the mat easier to clean and more durable during repeated outdoor use.
The waterproof, nonstick surface can be wiped down, rinsed with soap and water, or hosed off, according to the product details. It can also be folded for storage. Since the description does not provide a specific temperature limit, do not assume it can safely handle direct flame or contact with a hot grill. Check the instructions for placement and heat exposure.
At 48 by 30 inches, it may suit a smaller grilling area or a setup where you want a defined catch zone. It will not replace a cooking mat for delicate food, and it offers less coverage than the 48-by-65-inch UBeesize option. Measure the area around your grill before choosing.
Pros:
- Designed to catch grease and spills below the grill.
- Double-sided silicone coating and stitched edges.
- Can be rinsed, wiped, or hosed off.
- Folds for storage when not in use.
Cons:
- It is a ground-protection mat, not a surface for cooking food.
- The supplied product details do not state a specific heat limit.
Verdict: Consider this mat if you need a washable barrier under your grill and its 48-by-30-inch size fits your space.
WIBIMEN Copper Grill Mats: A Larger Set for Small or Delicate Foods
The WIBIMEN set has seven copper-colored mats, each measuring 15.75 by 13 inches. They sit on the grill grates and provide a nonstick surface for foods that may be awkward to cook directly on open bars, such as shrimp, vegetables, or small pieces of food. The product description also lists uses such as roasting and baking.
WIBIMEN states that the mats can withstand up to 500°F (260°C) for longer use, while also warning against direct contact with charcoal. That limit is a key factor when comparing these with the other cooking mats. A grill’s surface can be hotter than its general temperature setting, so use a suitable thermometer and follow the product’s specific instructions rather than relying on the grill dial alone.
The seven-piece set provides more mats than the RENOOK pack, and the description says the mats can be cut to size and cleaned by rinsing, wiping, or using the top rack of a dishwasher. The trade-off is that this is still a cooking-grate accessory, not a pad for protecting the deck beneath the grill.
Pros:
- Seven mats offer flexible coverage for different foods or grill zones.
- Listed heat resistance is up to 500°F (260°C).
- Nonstick design helps contain small foods on the cooking surface.
- Can be rinsed, wiped, or placed on the top rack of a dishwasher.
Cons:
- The product warns against direct contact with charcoal.
- It does not protect the deck or patio beneath the grill.
Verdict: The WIBIMEN set is a practical pick if you want seven cooking mats and can keep them within the stated heat limit and away from direct charcoal contact.
UBeesize Large Under Grill Mat: Broad Protection for Outdoor Spaces
The UBeesize mat measures 48 by 65 inches, making it the largest ground-protection option in this comparison. It is intended to sit below a grill or fire pit and help shield decks, patios, and grass from grease, residue, and sparks. Its fiberglass construction has a silicone coating on both sides, and the product description lists fire-retardant, waterproof, and oil-resistant properties.
The product states that it withstands heat up to 2,000°F. That is a product claim, not a reason to place the mat against a flame, hot coals, or a hot grill body. Use it as directed beneath equipment, and confirm the safety instructions for your specific grill and surface. This is not a mat for placing food on or for covering cooking grates.
For cleanup, the mat can be wiped or rinsed with soap and water or a garden hose. It folds for storage and comes with a storage bag, according to the supplied details. Its large footprint can be helpful around a wide grill, though it may be more mat than you need in a tight outdoor area.
Pros:
- Large 48-by-65-inch size covers a broad area beneath a grill.
- Double-sided silicone coating is described as waterproof and oil-resistant.
- Can be rinsed or hosed off and folds for storage.
- Includes a storage bag, according to the product details.
Cons:
- Its large size may be inconvenient for smaller spaces.
- It is a protective pad, not a cooking mat for food.
Verdict: Pick the UBeesize if you want wide ground coverage beneath your grill and have room to lay out and store a large mat.
GRILLART BBQ Grill Mats: Higher Listed Heat Resistance for Cooking
GRILLART’s set contains two reusable cooking mats for use on grill grates. The product description lists a heat resistance of up to 600°F and describes the mats as nonstick, scratch-resistant, and 0.39 millimeters thick. That stated temperature rating is higher than the limits listed for the RENOOK and WIBIMEN mats, which may make this set worth considering for grilling at higher temperatures within the product’s instructions.
The mats are intended to help keep foods such as vegetables, fish, and smaller items from falling through the grates. The description says they can be cut to size and cleaned with soap and water or in a dishwasher. Although the coating is described as more scratch-resistant than standard versions, use nonmetal utensils and avoid scraping the surface to help preserve it.
One trade-off is that the set includes only two mats, compared with six RENOOK mats or seven WIBIMEN mats. The product listing also does not provide a separate heat limit for longer sessions, so do not assume that the 600°F claim applies to every duration or grill setup. Follow the included directions and avoid direct flame or charcoal contact unless the instructions explicitly allow it.
Pros:
- Listed heat resistance is up to 600°F.
- Two reusable mats suit routine grilling needs.
- Nonstick surface is designed to help contain smaller foods.
- Can be cleaned with soap and water or in a dishwasher, according to the description.
Cons:
- Two mats may provide less coverage than the larger sets.
- The supplied details do not state a separate limit for extended use.
Verdict: The GRILLART set is a strong cooking-mat option if its stated 600°F limit suits your grilling style and two mats provide enough coverage.
How to Choose a Grill Mat for an Outdoor Grill
Decide Whether You Need a Cooking Mat or a Ground-Protection Mat
First, decide where the mat will go. Cooking mats sit on the grill grates and help keep small or delicate foods from falling through. Under-grill mats sit on the ground to catch grease, spills, or residue. They are not interchangeable: a ground mat is not meant to hold food, and a cooking mat will not protect a deck beneath the grill.
Check the Heat Limit and Use Instructions
Compare the stated temperature limit with the way you grill. The cooking mats here list different limits: RENOOK specifies up to 400°F for short use and 260°F for use longer than 30 minutes; WIBIMEN lists up to 500°F; and GRILLART lists up to 600°F. These claims do not mean a mat is safe against direct flame or coals. Follow the product instructions, and be especially careful with charcoal grills and high-heat cooking.
Measure the Grill or the Area Below It
For a cooking mat, check the size of the grates and decide how much of the cooking surface you want covered. Sets with several mats give you more pieces to arrange, while a two-piece set may be enough for a smaller grill. For an under-grill mat, measure the space you want to protect. The Linda’s Essentials mat measures 48 by 30 inches, while the UBeesize mat measures 48 by 65 inches.
Consider What You Plan to Cook
A cooking mat can be useful for small vegetables, shrimp, fish, and other foods that are difficult to manage on open grates. If you mainly grill larger cuts of meat, you may have less need for a mat. Some mats are also described for roasting or baking, but use them only with equipment and at temperatures allowed by their instructions.
Think About Cleaning and Storage
Nonstick surfaces can help reduce stuck-on food, but they still need cleaning after use. Check whether the mat is dishwasher safe or must be washed by hand. Under-grill mats may be rinsed or hosed off and folded, while larger models require more room to dry and store. Choose a design that fits your cleanup routine and available storage space.
Choose the Right Amount of Coverage
More pieces can be useful if you grill several foods at once or want spare mats, but they may take up more storage space. A large ground mat offers a wider catch area but may be awkward in a small patio. Match the number and dimensions of the mats to your actual setup instead of choosing by pack size alone.
Frequently Asked Questions
What is the difference between a grill cooking mat and an under-grill mat?
A cooking mat sits on the grill grates and provides a nonstick surface for food. An under-grill mat sits on the ground beneath the grill to catch grease, spills, and residue. Check the product’s intended use before placing any mat near a grill.
Can I use a grill mat on a charcoal grill?
Some cooking mats are listed for use with charcoal grills, but use instructions and heat limits vary. WIBIMEN specifically warns against direct contact with charcoal. Keep mats away from direct flame and hot coals unless the product instructions say otherwise.
Do grill mats stop food from getting grill marks?
A mat separates food from the grate bars, so the result can differ from cooking directly on the grates. RENOOK says its mat is thin enough to leave grill marks, but results can depend on heat, food, and how the mat is used.
Can grill mats be cut to size?
The RENOOK, WIBIMEN, and GRILLART product descriptions say their cooking mats can be cut to size. Before cutting, check the current product instructions and make sure the resulting shape will still be safe and practical for your grill.
Are grill mats dishwasher safe?
The RENOOK and WIBIMEN descriptions specify top-rack dishwasher use. GRILLART says its mats can be cleaned in a dishwasher or with soap and water. Follow the instructions supplied with the specific product you choose.
Which mat is best for protecting a deck or patio?
The Linda’s Essentials and UBeesize products are designed to go under a grill. Choose between them based on the amount of ground coverage you need: Linda’s Essentials measures 48 by 30 inches, while UBeesize measures 48 by 65 inches.
Final Recommendation
For cooking on the grates, the GRILLART set is the most compelling choice if you want the highest stated heat limit in this group and two mats are enough for your grill. Choose RENOOK or WIBIMEN if you want a larger multi-mat pack, while keeping their specific heat limits in mind. If your priority is protecting the surface beneath the grill, consider the Linda’s Essentials mat for a smaller footprint or UBeesize for broader coverage. In every case, use the mat only as directed and confirm that its size and heat limits match your setup.
