Whether you are securing a plaza in Dubai or a storefront in New York, the best bollard spacing depends on the use case.
For most commercial installations, the recommended center-to-center spacing is 1.0–1.5 meters (3.3–5 feet), with a minimum 915 mm (36 in) clear opening for ADA compliance.
Key data:
- Standard pedestrian/security spacing: 1.5 m (5 ft)
- ADA-required clear opening: 915 mm (36 in)
- High-security anti-ram spacing: 1.0–1.2 m (3.3–4 ft)
- Shared-bike/pedestrian spacing: 1.2 m (4 ft)
- Curb setback for storefront bollards: 0.5–0.6 m (20–24 in)
For most urban and commercial projects, the industry-standard distance between bollards is 1.5 meters (approx. 5 feet), measured from center to center.
This spacing is narrow enough to prevent passenger vehicles from passing through, yet wide enough to maintain a welcoming environment for pedestrians.
Clearance Space: This typically leaves a clear gap of about 0.9 to 1.2 meters (3 to 4 feet) between the bollard surfaces.
A professional security solution must not be a barrier for people with disabilities. Depending on your region, different laws apply:
North America (ADA): To be ADA compliant, you must ensure a minimum clear opening of 36 inches (915 mm).
Europe & UK: Standards like EN 17210 or Equality Act (Part M) often recommend a wider gap, typically between 1000 mm and 1200 mm, to accommodate larger motorized wheelchairs and strollers.
In high-threat environments where ram-raiding is a concern. The objective is to stop the vehicle's momentum entirely.
Bollards should be placed 1.0 to 1.2 meters (3.3 to 4 feet) apart, center-to-center.
Tighter spacing ensures that a vehicle cannot strike the gap at an angle and bypass the barrier. This is essential for crash-rated systems (K12/M50) protecting critical infrastructure.
To prevent crime, place bollards 1.5 meters (5 feet) apart and maintain a setback of 0.5 to 0.6 meters (2 feet) from the curb to avoid accidental damage caused by truck mirrors.
In areas where bicycles and pedestrians mix, spacing should be consistent. A gap of 1.2 meters (4 feet) is ideal to allow cargo bikes and strollers through while keeping cars out.
| Application | Center-to-Center (Metric) | Center-to-Center (Imperial) | Primary Goal |
| Standard Pedestrian | 1.5 Meters | 5 Feet | Accessibility & Basic Security |
| High Security/Anti-Ram | 1.0 - 1.2 Meters | 3.3 - 4 Feet | Total Vehicle Interdiction |
| ADA Compliant | 1.5 Meters | 5 Feet | Compliance (Min. 36" Clear Gap) |
| Utility/Asset Protection | 0.8 - 1.0 Meters | 2.5 - 3.3 Feet | Heavy Machinery Shielding |

FAQ
Q: What is the recommended spacing between bollards?
A: Recommended spacing is generally 1.0–1.5 meters (3.3–5 feet), depending on whether the site prioritizes security, accessibility, or pedestrian flow.
Q: How wide should bollards be for ADA compliance?
A: For ADA compliance, leave at least 915 mm (36 inches) of clear opening between bollards.
Q: What spacing is best for anti-ram bollards?
A: Anti-ram installations normally use 1.0–1.2 meters (3.3–4 feet) center-to-center spacing for K12/M50-rated setups.
Q: Should bollards be set back from the curb?
A: Yes. For storefront protection, set bollards back 0.5–0.6 meters (20–24 inches) from the curb to reduce accidental impact.
