17-Inch vs 22-Inch vs 28-Inch Griddle Covers: Which Size and Material Suits Your Outdoor Setup?

Your Blackstone griddle is an investment in outdoor cooking joy. Whether you use it for camping trips, tailgating, or weekend backyard feasts, protecting it from the elements is essential. Rain, dust, UV rays, and even curious critters can damage your griddle's surface and components over time. That's where a high-quality griddle cover comes in.

But with multiple sizes and materials available, choosing the right cover can feel overwhelming. Should you go with a 17-inch cover for portability, a 22-inch cover for versatility, or a 28-inch cover for full coverage? In this guide, we break down the differences between these three popular sizes, compare materials like polyester and vinyl, and help you match the perfect cover to your outdoor cooking lifestyle.

Why a Griddle Cover Matters for Long-Term Performance

A griddle cover is more than just a dust shield. It protects your cooking surface from moisture that can cause rust, prevents grease and debris from accumulating, and blocks harmful UV rays that can fade paint and degrade rubber seals. Without a cover, your griddle is exposed to temperature swings, bird droppings, and pollen that can compromise its performance.

Using a cover also reduces cleaning time. Instead of scrubbing off a layer of grime before each cookout, you simply lift the cover and start cooking. For griddle owners who store their equipment outdoors year-round, a durable cover is the single most effective way to extend the life of your investment.

• Prevents rust and corrosion on the cooking surface
• Blocks UV rays that fade paint and damage rubber seals
• Reduces cleaning time by keeping dust and debris off
• Extends the lifespan of your griddle by 2-3 years

17-Inch Griddle Covers: Compact Protection for Portable Cooking

If you own a compact 17-inch griddle, you likely value portability. These smaller griddles are perfect for camping, RV trips, or small balconies. The Adventure Ready 17" Range Combination is a popular choice for outdoor enthusiasts who need a lightweight yet durable cooking solution. A 17-inch cover is designed to fit snugly over these compact models, offering protection without adding bulk to your gear bag.

Materials for 17-inch covers typically include lightweight polyester with a water-resistant coating. Some models feature drawstring closures or elastic hems to keep the cover secure in windy conditions. While these covers are not as heavy-duty as larger options, they provide adequate protection for occasional outdoor storage and frequent transport.

• Ideal for camping, RV, and tailgating setups
• Lightweight and easy to pack with your griddle
• Typically made from water-resistant polyester
• Look for elastic hems or drawstrings for wind resistance

22-Inch Griddle Covers: The Versatile Middle Ground

The 22-inch griddle is one of the most popular sizes among home cooks. It offers enough cooking surface for family meals while remaining manageable for patio storage. The 22" XL Griddle Pellet Grill Combo Cover is a great example of a purpose-built cover that accommodates both the griddle and a pellet grill attachment. This size is ideal for those who want full coverage without the bulk of a 28-inch cover.

22-inch covers often use thicker materials like heavy-duty polyester or vinyl with a waterproof backing. Many include padded handles, air vents to reduce condensation, and adjustable straps to prevent the cover from blowing off. If you store your griddle on a deck or balcony, a 22-inch cover with UV protection will keep it looking new for years.

• Fits most standard 22-inch griddles and combo units
• Heavy-duty materials offer better weather resistance
• Look for air vents to prevent moisture buildup
• Adjustable straps help secure the cover in high winds

28-Inch Griddle Covers: Full-Size Protection for Large Setups

For serious outdoor cooks with a 28-inch griddle, a full-size cover is non-negotiable. The National Griddle Week 28" Griddle Bundle includes a griddle and essential accessories, making a matching cover a smart add-on. A 28-inch cover provides complete coverage for the cooking surface, shelves, and side tables, shielding everything from rain, snow, and sun.

These covers are typically made from the most durable materials, such as marine-grade vinyl or 600D polyester with a waterproof laminate. Many feature reinforced seams, rust-resistant grommets, and tie-down loops for extra security. If your griddle lives outside year-round, a 28-inch cover with a high denier rating and UV stabilizers is the best investment you can make.

• Full coverage for griddle, shelves, and side tables
• Marine-grade vinyl or 600D polyester for maximum durability
• Reinforced seams and grommets prevent tearing in wind
• UV stabilizers protect against sun damage and fading

Material Comparison: Polyester vs Vinyl vs Canvas

The material of your griddle cover directly impacts its durability, weight, and water resistance. Polyester covers are lightweight and affordable, making them a good choice for portable griddles. However, they may degrade faster under constant sun exposure. Vinyl covers offer excellent waterproofing and UV resistance but can be heavier and less breathable, which may lead to condensation inside.

Canvas covers are a premium option, often treated with wax or waterproof coatings. They are breathable, durable, and environmentally friendly, but they come at a higher price point. For most outdoor setups, a heavy-duty polyester cover with a waterproof coating strikes the best balance between cost, weight, and protection. Always check the denier rating—higher numbers mean thicker fabric.

• Polyester: lightweight, affordable, best for portable griddles
• Vinyl: waterproof, UV-resistant, heavier, may trap moisture
• Canvas: premium, breathable, durable, higher cost
• Look for a denier rating of 600 or higher for outdoor storage

How to Measure Your Griddle for the Perfect Fit

Before buying a cover, measure your griddle from left to right (width), front to back (depth), and top to bottom (height). Include any side shelves, handles, or propane tank holders in your measurements. A cover that is too small will leave parts exposed, while one that is too large may flap in the wind and allow debris underneath.

Most manufacturers provide a sizing chart that matches cover dimensions to griddle models. If your griddle has a hood or a built-in pellet grill, look for a combo cover that accommodates both. The 22" XL Griddle Pellet Grill Combo Cover is specifically designed for such setups, ensuring a snug fit that protects every component.

• Measure width, depth, and height including side tables
• Check manufacturer sizing charts for exact fit
• Consider combo covers for griddles with pellet grill attachments
• A snug fit prevents wind damage and debris accumulation

Storage Conditions and Cover Longevity

Where you store your griddle affects how long your cover will last. Griddles kept in direct sunlight will degrade even the best UV-resistant covers over time. If possible, park your griddle in a shaded area or under a patio roof. During heavy rain or snow, consider using a secondary waterproof layer or a cover with a high hydrostatic head rating.

Regular cleaning also extends cover life. Rinse off dirt and bird droppings with a garden hose, and let the cover dry completely before putting it back on. Avoid folding or storing the cover when wet, as mildew can form. With proper care, a quality cover can last 3-5 years, protecting your griddle through countless cookouts.

• Store griddles in shade to reduce UV exposure
• Use a cover with a high hydrostatic head for wet climates
• Clean covers regularly to prevent mildew and staining
• Let covers dry completely before folding or storing

Choosing the right griddle cover comes down to your griddle size, storage environment, and how often you cook outdoors. Whether you need a compact cover for a portable 17-inch model or a heavy-duty cover for a full-size 28-inch setup, investing in the right material and fit will keep your Blackstone performing at its best for years. For a versatile option that fits most standard setups, explore the 22" XL Griddle Pellet Grill Combo Cover and give your griddle the protection it deserves.
