Square and frame-supported bed nets hang straight to the floor with the least inward-draping fabric, while hoop and canopy nets hang from a single point and stay simplest to mount.
A net that sags inward leaves a gap between fabric and mattress — just enough room for a mosquito to feed from the outside. The shape of the net decides whether that gap exists at all, and it decides how much hardware you have to put into your ceiling.
There are four common designs sold for beds today: canopy nets, hoop nets, square (box) nets, and frame-supported nets. They differ in three practical ways — how many ceiling anchors they need, how straight the walls hang, and how easy it is to get in and out.
Canopy Nets And Hoop Nets: Single-Point Hanging
Canopy and hoop nets suspend from one ceiling hook, which makes them the fastest styles to install and the least demanding on your ceiling.
A hoop net uses a round metal or fiberglass hoop at the top, with a fabric loop or hook fitting for suspension. Hoop diameters run 55 or 75 cm, and a square version of the hoop style uses a 55 or 75 cm square frame — still hanging from that one central point.
Canopy style nets are the draped, decorative end of the family. A classic cotton bed canopy with a 65 cm fiberglass hoop stands 250 cm high, and the fibreglass keeps its shape while the net falls generously around the mattress and bed frame.
The trade-off is honest and worth knowing before you buy: with a round hoop, fabric tends to hang inward. That inward drape is exactly where a mosquito reaches the sleeper from outside the net. If you want straight walls, a hoop is not the shape for you.
Square And Frame Nets: Straighter Walls, More Anchors
Square and frame-supported nets hold the fabric out in straight walls, and they trade that for more mounting hardware.
A square net uses a cross-frame at the top. That frame keeps the net falling in a straight shape with little to no fabric hanging inward, and the side opening makes entry and exit easy. Square nets also hang from a single fixing point, so you get the straight-wall benefit without four anchors.
Mesh count matters here too. A Red Cross procurement document lists a square double net at 2m x 2m x 2m, calls it the most comfortable net for a double bed, and rates it more comfortable than the spider type.
Frame-supported nets go one step further. A box net in the single/twin size (43″ × 83″, or 110 × 210 cm) has a sewn sleeve along the top edge. You thread a lightweight curtain rod or wooden dowel through each side, join the rods into a rectangle, and suspend that rectangle from four ceiling hooks — one per corner. The frame holds the net square and the drapes fall straight to the floor. Some setups skip the rods entirely and use a hidden curtain-rod frame or a bamboo or wood frame instead.
Comparing The Four Styles Side By Side
| Net Style | Mounting And Shape | Best For |
|---|---|---|
| Canopy | Single ceiling hook, draped fabric | Bedrooms where look matters more than straight walls |
| Hoop (dome) | One point, round 55 or 75 cm hoop, fabric tends inward | Quick single-hook installs over a single bed |
| Square hoop | One point, 55 or 75 cm square frame, straighter drape | Renters who want straight walls with one anchor |
| Square (box) | Top cross-frame, one fixing point, side opening | Double beds needing room-like, sag-free walls |
| Frame-supported box | Rods in top sleeve, four corner hooks, straight to floor | Permanent setups on a bed with four anchor points |
| Impregnated square double | 2m x 2m x 2m, one fixing point | Double beds in high-mosquito areas |
| 156-mesh rectangular | 200 x 210 x 200 cm, WHO minimum mesh | Sleepers who want verified fine mesh |
Installation Basics And Mistakes To Avoid
Every style installs with the same logic: mount the anchor, hang the net, then adjust the hem so the bottom just touches the floor.
For a hoop or canopy net, drill a ceiling hook over the center of the bed, attach the net by its cord or elastic loop, and adjust the length. A hole-free option exists too — run a horizontal wire and hang the net from that instead. For a frame-supported box net, thread the rods through the sewn sleeve, join them at the corners into a rectangle, and hang that rectangle from four ceiling hooks.
The most common mistake is buying a round hoop for a wide bed and then discovering the inward drape leaves fabric resting against the mattress edge. That contact point is where mosquitoes get through. If straight walls matter to you, choose a square or frame-supported design from the start. If you would rather compare tested options before drilling anything, this roundup of the best bed mosquito net picks covers the current favorites.
One more note on mesh: Finer mesh blocks more, but it also cuts airflow, so a 156-mesh square net is a sensible middle ground for most bedrooms.

FAQs
Which style keeps fabric from hanging inward?
Square and frame-supported nets. A square net uses a top cross-frame that holds the fabric in a straight fall with little to no inward drape, and a frame-supported box net threads rods through a top sleeve so the walls drop straight to the floor. Round hoop and canopy nets drape inward, which can let a mosquito reach you from outside.
How many ceiling hooks does each design need?
Canopy, hoop, and square nets all hang from a single fixing point. Frame-supported box nets need four ceiling hooks, one at each corner. If you rent or do not want to drill four holes, a single-point square net gives you straight walls with only one anchor in the ceiling.
What mesh count should a bed net have?
Finer mesh blocks more insects but reduces airflow, so 156 mesh is a practical balance for most bedrooms.
