When you're shopping for a hammock, one of the first decisions you'll face is choosing between a single and a double size. It seems simple enough—single for one person, double for two—but the reality is more nuanced. Many solo campers choose doubles, and some couples squeeze into singles. The choice comes down to weight capacity, comfort, portability, and how you actually plan to use your hammock.

Here's everything you need to know to make the right call.

What's the Real Difference?

A single hammock is designed for one person. Most singles have a width in the 4- to 5-foot range. They're compact, lightweight, and ideal for solo backpackers who want to save every ounce.

A double hammock is wider—typically 5 to 6 feet across. It offers more space for lounging, gives you the option to share with a partner, and—perhaps surprisingly—is often the preferred choice even for solo campers who value extra room.

The key distinction, however, is weight capacity—and that's where many buyers get confused.

Weight Capacity: The Numbers That Matter

Single Hammock Weight Capacities

Single hammocks typically support 300 to 400 pounds, with ultralight models rated closer to 250 pounds.

Some specific examples:

  • ENO SingleNest: 400 lbs

  • Kammok Roo Single: 400 lbs

  • Wise Owl Outfitters Single: 400–500 lbs

  • Gold Armour Single: 500 lbs

Double Hammock Weight Capacities

Double hammocks generally offer 400 to 500 pounds of capacity, with ultralight models closer to 350 pounds.

Examples include:

  • ENO DoubleNest: 400 lbs

  • Kammok Roo Double: 500 lbs

  • Wise Owl Outfitters Double: 500 lbs

  • Kootek Double: 500 lbs

  • MalloMe Double: 661 lbs (300 kg)

Some heavy-duty double hammocks push even higher—600 lbs or more—with reinforced 210T ripstop nylon and triple-layer stitching.

The 75% Rule: Why Capacity Isn't Everything

Here's a critical point many buyers overlook: you should never max out a hammock's stated weight capacity.

Safety experts recommend using only 75% to 80% of a hammock's rated capacity. If you weigh 200 pounds, choose a hammock rated for at least 250 pounds. This safety margin protects against unexpected stress, extends your hammock's lifespan, and accounts for dynamic forces—the extra stress created when you shift positions, rock, or get in and out.

For a double hammock used by two people, this rule is even more important. Two bodies create exponentially more dynamic force than one. If you and your partner weigh a combined 350 pounds, look for a hammock rated at 450–500 pounds minimum to stay within the safety margin.

Single Layer vs Double Layer: Another Capacity Factor

Beyond single vs double size, there's also single vs double layer construction. Double-layer hammocks use two layers of fabric, typically offering 50–150 lbs more weight capacity than single-layer versions of the same material.

A double layer also provides:

  • A firmer lay with less stretch

  • The ability to insert a sleeping pad between layers for insulation

  • Reinforced durability at the cost of extra weight (about 7 ounces more)

If you're near the upper end of a single-layer hammock's weight limit, a double-layer version can give you the extra capacity and peace of mind you need.

Comfort: Why Bigger Often Means Better

Here's the counterintuitive truth: most people choose a double hammock for comfort, not because they plan to hang with a friend.

A double hammock's extra width allows you to lie diagonally—the secret to a flat, comfortable sleep in a gathered-end hammock. This diagonal position provides better spinal alignment, reduces pressure points, and eliminates the "banana" shape that makes single hammocks uncomfortable for overnight sleeping.

Double hammocks also give you room to stretch out completely, move naturally during sleep without waking up, and wrap the extra fabric around yourself for warmth or privacy.

Single hammocks, while still comfortable for lounging, can feel cramped or confined—especially for taller individuals or side sleepers.

Portability: Where Singles Win

If weight and pack size are your top priorities, single hammocks have a clear advantage.

A single hammock saves weight—a significant plus for backpackers. The ENO SingleNest weighs just 16 ounces; the Kammok Roo Single comes in at about 13 ounces.

A double hammock is heavier and bulkier but offers more space and versatility. The tradeoff is clear: weight savings vs. comfort and capacity.

Which Size Is Right for You?

Choose a Single Hammock If:

  • You're a solo camper who prioritizes lightweight and compact gear

  • You're backpacking or thru-hiking where every ounce counts

  • You weigh under 250 pounds and don't need extra capacity

  • You prefer a minimalist setup and don't mind less lounging space

  • You never plan to share your hammock with another person

Choose a Double Hammock If:

  • You want the most comfortable sleep with room to lie diagonally

  • You plan to share with a partner (even occasionally)

  • You weigh over 200 pounds and want a generous safety margin

  • You're car camping, overlanding, or setting up a basecamp where weight isn't critical

  • You value versatility—the option to sprawl solo or snuggle with someone else

The Smart Money Picks

For most buyers, a double hammock with a 400–500 lb capacity is the sweet spot. It gives you room to grow, accommodates dynamic forces safely, and works whether you're flying solo or sharing.

If you're a dedicated ultralight backpacker under 200 lbs, a single hammock rated for 300–400 lbs will serve you well. Just remember the 75% rule and don't push the limits.

And if you're shopping for two people with a combined weight over 350 lbs, look for heavy-duty double models rated at 500–600 lbs with 210T ripstop nylon or double-layer construction for maximum durability.

The Bottom Line

Single hammocks are lighter, more packable, and perfectly adequate for solo campers who prioritize weight savings. Double hammocks offer higher weight capacity, superior comfort through diagonal lying, and the flexibility to share—making them the better choice for most recreational users.

As REI's experts put it: "Most people choose a double for comfort, not necessarily because they plan to hang with a friend". The extra space, higher weight capacity, and room to move make doubles the smarter long-term investment for all but the most weight-conscious backpackers.

Choose based on your weight, your camping style, and your comfort priorities—and always leave a safety margin between your total load and the manufacturer's rating. Your back (and your safety) will thank you.
