How High Should a Privacy Screen Be?

The short answer

A privacy screen must reach above the highest line of sight between the viewer’s eyes and the top of what you want hidden, measured at the screen’s position, plus a safety margin. If the viewer’s eyes and what you want hidden are both below the screen top, no sightline can pass over it. That is why a 1.80 m (5 ft 11 in) screen is enough against a neighbor standing on level ground (1.50 m (5 ft 0 in) needed in the example below), but not against people looking down from above.

Calculated heights for common situations

All values come from the same geometry engine as the planner. “With margin” adds 20 cm.

Screens in the upper-floor examples stand right beside the area, which is the lowest workable position. Placed further away, they would need to be taller — see privacy screen placement.

The four factors that decide the height

1. How high the viewer’s eyes are

This is the biggest factor. Each story adds roughly 3 m (10 ft). A deck, a slope or even a step raises a ground-level viewer. Measure relative to your ground.

2. How far away the viewer is

A distant viewer’s sightlines are flatter; a close, high viewer’s are steep. Flatter lines can be caught by lower screens placed near your space.

3. Where the screen stands

Against views from above, the closer to your private area, the lower — and wider — the screen can be. Against views from below, the opposite.

4. What you want to hide

Typical heights above the floor of the area:

What to hide	Typical height
Lawn, pool water surface, ground	0
People lying on sun loungers	0.90 m (3 ft 0 in)
Bathers in a hot tub (heads and shoulders)	1.10 m (3 ft 8 in)
Adults seated at a table or on a sofa	1.20 m (4 ft 0 in)
Children playing	1.50 m (5 ft 0 in)
Adults standing	1.80 m (5 ft 11 in)

These are planning values, not standards; adjust them to the people and furniture involved.

Things that make a screen effectively lower

• Gaps. A panel mounted above a gap, or slatted and lattice designs, block less than their outline suggests.
• Plants. Hedges and climbers are only as tall as the part dense enough to block a view.
• Ground level. A screen on lower ground than the area is effectively shorter by the difference.

Geometry is not permission

A calculated height tells you what would block the view. It does not tell you what you may build: fence and screen height limits, setbacks and permits differ widely between and within countries. Check local rules before building, and consider talking to the neighbor — a shared solution is sometimes simpler than a taller screen.

Frequently asked questions

Is 6 feet (1.8 m) tall enough for a privacy screen?

It is enough when the people looking are standing on the same level as you and cannot see over it — their eyes are below the top. Against decks, sloping lots and upper floors, 1.8 m is often not enough unless the screen stands close to what you are hiding.

How much safety margin should I add?

10–30 cm (4–12 in) is typical. Use more when your measurements are estimates, when taller viewers are likely, or when the screen is far from the area (errors grow with distance). The margin is added on top of the geometric minimum.

Do I need to hide the whole height of a person?

Usually you only need to hide what you care about — faces and upper bodies of seated people is a common goal. Hiding standing people from an upper floor is much more demanding. Pick the height to hide deliberately; it changes the result a lot.
