Building a living evergreen privacy fence is one of the highest-return landscape investments you can make. Whether you are blocking road noise, screening a neighbor's two-story window, or creating a windbreak around a backyard pool, choosing the right tree spacing determines how quickly your hedge fills in—and how healthy those trees remain 10 to 20 years from now.
In this complete spacing guide from American Tree Nursery Direct, we compare our three bestselling evergreen privacy trees in the Privacy Hedges & Fast-Growing Evergreens collection and give you an exact tree-count calculator for 25 ft, 50 ft, 100 ft, and 150 ft property lines.

2. Privacy Hedge Spacing & Tree-Count Calculator Table
Use the formula (Property Line Length ÷ Spacing in Feet) + 1 to calculate the exact number of trees needed from post to post:
| Privacy Tree Variety | Spacing Setting | 25 ft Line | 50 ft Line | 100 ft Line | 150 ft Line |
|---|---|---|---|---|---|
| Thuja Green Giant | Fast Privacy Screen (5 ft on-center) | 6 trees | 11 trees | 21 trees | 31 trees |
| Thuja Green Giant | Standard Windbreak (6 ft on-center) | 5 trees | 9 trees | 18 trees | 26 trees |
| Leyland Cypress | Fast Privacy Screen (6 ft on-center) | 5 trees | 9 trees | 18 trees | 26 trees |
| Leyland Cypress | Acreage Screen (8 ft on-center) | 4 trees | 7 trees | 14 trees | 20 trees |
| Emerald Green Arborvitae | Tight Formal Hedge (3 ft on-center) | 9 trees | 18 trees | 34 trees | 51 trees |
| Emerald Green Arborvitae | Standard Screen (4 ft on-center) | 7 trees | 14 trees | 26 trees | 39 trees |
3. Single Row vs. Staggered Double Row (Zig-Zag Planting)
If you have at least 10 to 14 feet of depth along your boundary and want maximum sound reduction and instant sightline blocking, plant a staggered double row (zig-zag pattern):
- Space two parallel rows 6 feet apart.
- Space trees 6 to 8 feet apart within each row, offsetting the back row so each tree sits centered behind the gap in the front row.
- Staggered rows improve airflow around lower branches, prevent bare gaps if one tree ever sustains storm damage, and cut street traffic noise noticeably faster than a single line.
