3m x 4m Pergolas

3m x 4m pergolas are one of the most practical sizes for garden use, offering extra space for seating, dining, or larger setups. This size provides a good balance between coverage and usability, making it ideal for patios and outdoor living areas.

It’s a popular choice for customers who want more room to move or accommodate furniture without stepping up to a much larger structure. The rectangular shape also works well for dining tables, lounge sets, or hot tub areas.

You’ll find 3m x 4m pergolas across a range of styles and roof options within our Retractable Roof Pergolas, Hard Top Pergolas, and Metal Pergolas collections.

Why Choose a 3m x 4m Pergola

A 3m x 4m pergola — often written 3x4 — is a rectangular structure that offers more room than a 3x3. It's a practical size for a full dining set, a larger lounge suite or a hot tub with seating alongside.

  • Generous rectangular footprint
    Three by four metres — around twelve square metres of usable cover.
  • Room for more
    Shelters a six-seat dining set, a large corner sofa or a hot tub with chairs.
  • Roof options
    Choose a fixed roof, a solid hard top, or a retractable canopy.
  • Aluminium or steel frames
    Rust-free aluminium or powder-coated steel for a permanent structure.
  • Great for dining
    The longer shape suits dining tables and lounge layouts.
  • Supplied as a kit
    Every 3x4 pergola ships as a self-build kit with frame, fixings and instructions.

What Fits Under a 3m x 4m Pergola?

As a rule of thumb, a 3x4 pergola covers one of the following:

  • A six-seat dining set
  • A large corner sofa or lounge suite
  • A hot tub with seating alongside

Measure your furniture and leave room to move around it comfortably before you decide.

Roof and Style Options

A 3m x 4m pergola comes in several styles. For adjustable shade, see our Retractable Roof Pergolas; for a solid, all-weather cover, our Hard Top Pergolas; and for the frame itself, our Metal Pergolas.

Smaller Space?

If a 3x4 is more than you need, a 3m x 3m pergola suits compact patios and smaller seating areas.

Finish the space with seating from our Rattan Patio Furniture or Garden Furniture & Outdoor Living range.

FAQ: 3m x 4m Pergolas

How big is a 3m x 4m pergola?

A 3m x 4m pergola is three metres by four metres — around twelve square metres of cover. The rectangular shape gives you noticeably more room than a 3x3, which makes it a practical size for dining, a full lounge set or a hot tub with seating alongside.

What fits under a 3x4 pergola?

A 3x4 pergola covers a six-seat dining set, a large corner sofa, or a hot tub with a couple of chairs beside it. The longer rectangular footprint works especially well for dining tables and lounge suites.

Should I choose a 3m x 3m or 3m x 4m pergola?

Choose a 3m x 4m pergola if you want room for six-seat dining or a larger lounge set. If you're working with a compact patio or only need to cover a small seating area, a 3m x 3m pergola is the better fit.

Can you get a 3m x 4m pergola with a roof or retractable canopy?

Yes. A 3m x 4m pergola comes with a fixed roof, a solid hard top, or a retractable canopy for adjustable shade. See our Retractable Roof Pergolas and Hard Top Pergolas.

What frame materials do 3x4 pergolas come in?

Most 3x4 pergolas have a rust-free aluminium or powder-coated steel frame. Aluminium is light and won't rust; steel gives maximum strength for a permanent structure. Browse frames in our Metal Pergolas range.

Are 3x4 pergolas supplied as kits?

Yes — every 3x4 pergola is supplied as a self-build kit with the frame, fixings and instructions included. Given the larger size, assembly is easier with a second pair of hands.

Browse our 3m x 4m pergola range to compare frames, roof options and styles, and find a roomy rectangular structure for dining or lounging.
