A straight path is the quickest route from A to B, and in a courtyard, side return or narrow coastal strip that is precisely the problem. It tells the eye where the garden ends before a visitor has taken three steps. A gentle curve does the opposite: it conceals part of the route, so the boundary drops out of sight and the plot reads as longer and wider than it measures. In a space of six by eight metres, a path that swings half a metre either side of a central axis can add the illusion of a couple of metres of depth.
There is a practical gain as well. Curves slow footsteps. You notice the planting at hip level, the scent of rosemary warmed by a south-facing wall, the change in sound as gravel gives way to paving. On an exposed coastal site, a winding route also interrupts the wind's run across the garden, breaking its fetch and sparing the plants behind it.
The mistake most often made is a curve so tight it reads as a kink. Aim for generosity: a walkable bend wants a radius of at least 1.5 metres, and 2 to 3 metres looks far better in a small garden because it feels like a decision rather than an accident. Lay out the line with a length of hose or a rope of sand before committing a spade to the ground, then stand at one end and look along it. If you can see the whole garden from the doorway, the curve is not doing its job.
Curves are more forgiving than straight runs when it comes to materials, because cut edges and awkward joints disappear. Clay pavers laid in a sweeping arc look superb but need cutting; self-binding gravel, hoggin or a resin-bound surface follows a curve effortlessly and is far kinder on the knees than loose stone.
On coastal sites, wind is the deciding factor. Light 10 mm gravel will migrate off an exposed path within a season, so choose a graded self-binding mix, a stabilised gravel grid, or resin-bound aggregate that knits together and resists salt-laden gusts. Permeable surfaces matter too, particularly where the path crosses heavy clay that already struggles in a wet winter.
Excavate to about 150 mm for a gravel path, then compact 75–100 mm of MOT Type 1 sub-base with a plate compactor, working in two layers. Add a woven geotextile over the sub-base to stop the decorative surface sinking into the base, then top with your chosen material. For gravel, 30 mm of self-binding is plenty; for paving, a 30–40 mm bedding course of sharp sand over a concrete or compacted base.
Edging holds the whole thing together, literally. Steel edging is slim and near-invisible; timber is cheaper but rots where the ground stays damp; brick or stone setts on edge suit a traditional cottage garden and give the curve a crisp outline. Whatever you choose, set it to the finished height of the path so a mower can run over it without catching.
The curve is only half the story — the planting around it does the softening. Keep low, spreading plants at the inner edge so they do not crowd the walkway, and allow taller, looser planting at the outer edge to lean over the path and blur the line.
A curved path asks a little more of you than a straight one. Edges need trimming twice a year, and gravel benefits from a rake and a top-up each spring to replace what has migrated into the borders. In shaded or coastal gardens, watch for algae and moss on hard surfaces — a stiff brush and a diluted vinegar wash in early spring deals with most of it without harsh chemicals.
Cut back the plants that flop over the inner edge after flowering, so the line stays legible, and resist the urge to fill every gap. The curve is the structure of your garden; a little breathing space around it is what makes a modest plot feel generous, calm and far larger than its measurements suggest.
