Monument Grills 4-Burner vs 6-Burner Propane Gas Grill: Which Is Better for Your Backyard?

If you're trying to decide between the Monument Grills 4-burner and 6-burner propane gas grills, the key factors are how many people you usually cook for and how much space you have on your patio. Both grills are made of stainless steel and come with great features like sear burners, LED control knobs, and ClearView lids. However, they differ quite a bit in cooking space, heat output (BTUs), price, and size. This comparison will help you understand the important differences so you can pick the best grill for your backyard BBQ setup.

The short answer: For most family households that grill regularly but don't consistently host large parties of 10+ people, the Monument Grills 4-burner (Model 35633, ~$579) is the better buy. It delivers 72,000 BTU across approximately 723 sq in of cooking area - enough for 6–10 people - while being lighter, more compact, and roughly $120 less expensive than the 6-burner. Choose the Monument Grills 6-burner (Model 77352) only if you frequently entertain large groups or need maximum heat zone flexibility across its 900 sq in surface.

Monument Grills 4-Burner vs 6-Burner with Side Burner: How They Compare at a Glance

The headline takeaway: the 6-burner gives you roughly 25% more cooking area and 17% more BTU output for about 21% more money - but it's less portable around a patio because it takes up significantly more space and weighs over 40 pounds more.

Cooking Area, Capacity and BTU Performance

When you're comparing propane grills with different numbers of burners, cooking capacity is the most important factor, and a broader Monument Grills decision guide can also help match features and size to your needs. It decides how much food you can cook at the same time and whether you'll need to cook in batches or all at once.

The Monument Grills 4-burner Model 35633 propane grill offers about 72,000 BTU from its four main burners, plus a side burner and a side sear burner. It has a total cooking area of roughly 723 square inches (513 sq in for the main grilling surface and about 210 sq in for warming racks). That's enough space to cook around 25–35 burgers at once, comfortably feeding 6–10 people and making it ideal for most family outdoor cooking without having to cook in shifts.

The Monument Grills 6-burner Model 77352 stainless steel grill steps it up with 84,000 BTU from six stainless steel main burners plus a side burner. Some versions even reach up to 96,000 BTU when you include sear zones. It offers about 900 square inches of total cooking space (634 sq in primary plus 266 sq in warming racks), so you can handle 35–40 burgers at once and feed 8–12 or more people.

But it's not just about the numbers. The 6-burner's extra burners give you more flexibility with heat zones. You can have two burners blazing hot for searing steaks while keeping others on low for indirect cooking. This is perfect if your meal preparation often involves cooking different foods at different temperatures at the same time. The 4-burner has a sear burner too, but it doesn't offer as much flexibility.

Keep in mind, though, that a high BTU rating alone doesn't guarantee better performance. How heat spreads across the grill matters just as much. More burners usually mean more even heat because each burner covers less area. But bigger grills can sometimes have cold spots if you don't place your food carefully.

Winner: 6-Burner (Model 77352) – It offers more cooking space, higher BTU output, and better heat zone control. That said, the 4-burner is plenty for groups under 10 and heats up faster without wasting fuel.

Price and Value Proposition

Price is important both when you buy the grill and over the long term. Propane grills are favored for their convenience and quick setup, and Monument 4-burner gas grills still heat up quickly—usually in 5 to 10 minutes. They're also relatively clean after cooking, with no charcoal ash to deal with, and propane is an easy way to get dinner started on a weeknight without charcoal prep. But how much propane you use depends on how many burners you have.

The Monument Grills 4-burner Model 35633 typically costs around $579 in stainless steel with side and sear burners. The 6-burner Model 77352 stainless steel gas grills run about $699 and include extras like a rotisserie kit and a side burner.

If you look at price per square inch of cooking space, the 6-burner actually gives you slightly better value—about $0.78 per square inch compared to $0.80 for the 4-burner. So if you need the extra space, you're getting a bit more grill for your money.

But propane use tells a different story. Running all burners at full power, the 6-burner’s 84,000 BTU rating uses nearly a gallon of propane per hour (since one gallon is about 91,000 BTU). The 4-burner at 72,000 BTU uses roughly 0.8 gallons per hour. At about $3.50 per gallon, that's $3.50 versus $2.80 per hour at full blast. When grilling normally with 2–3 burners on medium, both use about $1–$2 worth of propane per hour. So the 6-burner costs more if you're always using all burners. You can easily replace or refill standard propane tanks, though, keeping fuel costs manageable for either grill, and you can use Monument Grills' retail partner store locator to find nearby retailers for fuel and accessories.

Both models come with an 8-year limited warranty on burners, though electronic parts like ignitions have shorter coverage. A good warranty shows the manufacturer's confidence in the grill's durability. Both grills have heavy stainless steel or cast iron grates that hold heat well and help the grill last longer.

Winner: 4-Burner (Model 35633) – It's $120 cheaper upfront and uses less propane. The trade-off is that the 6-burner offers slightly better value per square inch and comes with extras like a rotisserie kit that you'd pay extra for if you bought separately.

Setup and Storage Requirements for Outdoor Cooking

Your backyard space can really affect how enjoyable your grill is to use. Before buying, measure your patio or deck, check gate widths, and think about how often you'll need to move the grill, because the 4-burner is designed for tighter spaces while the 6-burner makes more sense in open layouts.

The Monument Grills 4-burner Model 35633 measures about 54.1" wide × 22.5" deep × 46.3" high and weighs around 101 pounds. The 6-burner Model 77352 is bigger and heavier at roughly 61.8" wide × 23.6" deep × 45.9" high and 143 pounds. That's almost 8 inches wider and over 40 pounds heavier.

Assembly gets more complicated as the grill gets bigger. Both need full assembly with basic tools, but the 6-burner has more parts like extra burners, flame tamers, a bigger cart, and more casters, so it will take longer to put together. When buying, check the quality of parts because that affects how long the grill will last.

For moving the grill, the 6-burner has four heavy-duty swivel locking casters, but at 143 pounds, it's a two-person job to get it through narrow gates or over uneven ground. The 4-burner is lighter and easier to move, making it better for smaller spaces, but neither model is meant for camping and the 4-burner is only the more movable of the two, not a true portable travel grill. Both models have side shelves for extra prep space and these can fold down to save room when storing.

Propane grills make less smoke than charcoal, so you can place them closer to seating areas, but always follow safety guidelines about keeping them away from walls and railings.

Winner: 4-Burner (Model 35633) – It's lighter, narrower by nearly 8 inches, and easier to assemble, move, and store. The trade-off is that if you've got plenty of space and don't plan to move your grill, the bigger 6-burner size won't be a problem.

Monument Grills 4-Burner vs 6-Burner: Which Should You Choose?

• Choose the Monument Grills 4-burner if you usually cook for 4–8 people, have moderate backyard or patio space, want premium features like a sear burner, ClearView lid, and LED knobs without paying for extra capacity you won't use, or if you prefer lower upfront cost and fuel use. It's also the more convenient choice for everyday outdoor cooking, and it's easier for beginners learning to manage heat zones.

• Choose the Monument Grills 6-burner if you often entertain 8–12+ people, want the most cooking flexibility with multiple heat zones, plan to use extras like a rotisserie kit, and have plenty of outdoor space where the larger size and weight won't be an issue. It's the better fit if you want a larger station that can work alongside accessories such as a griddle.

For most backyard grillers who cook regularly but don't host big parties all the time, the 4-burner Model 35633 is the best overall choice. It meets most needs at a lower price with enough power and features to help you start cooking faster for routine family use. The 6-burner is worth it only if you really need the extra space and zone control on a regular basis.

Many Monument gas grills come with multiple burners for versatile cooking, and Monument Grills offers solid builds in both sizes. Both Monument models include integrated thermometers to help you monitor cooking temperatures accurately.

Frequently Asked Questions

Can I upgrade from a 4-burner to a 6-burner Monument Grills later?

No. The burner count, frame width, grate dimensions, and cart structure are fundamentally different between the two size classes. This isn't a modular system - you cannot add two main burners to extend a 4-burner into a 6-burner. You'd need to purchase a new grill entirely. You can replace or add accessories like a side burner, but the core burner number is fixed by the grill's design.

Which Monument Grills propane grills are better for beginners?

The 4-burner is the better choice for beginners. It has fewer burners to manage, which makes learning heat zone control simpler. The smaller cooking area is less intimidating, and there's less flame complexity to deal with during your first sessions. Propane grills offer quick ignition for easy cooking and allow for easy adjustments to heat levels, so both models are beginner-friendly in that sense - but the 4-burner has a gentler learning curve overall.

How much propane do these Monument Grills models consume per hour?

At full power with all burners on high, the 4-burner (72,000 BTU) consumes roughly 0.8 gallons of propane per hour, while the 6-burner (84,000 BTU) uses approximately 0.9–1.0 gallons per hour. In typical use, selecting only the burners you need helps reduce propane consumption - 2–3 burners on medium - and drops usage to about 30–50% of those figures. At an average propane cost of around $3.50 per gallon, a typical grilling session costs roughly $1–$2 per hour for either model under normal conditions, with the 6-burner running slightly higher when more burners are engaged. Large outdoor gas grills offer ample cooking space for gatherings, but that extra capacity does carry a proportional fuel cost when fully utilized, which is useful context when comparing propane grill specs on a retailer page.
