How can I determine the appropriate height and diameter for bollards?

To determine the appropriate height and diameter for bollards, consider the purpose, location, and surrounding environment. Firstly, assess the level of protection required, as taller and wider bollards provide greater impact resistance. Typical height ranges between 900-1500mm, while diameters vary from 60-300mm. Secondly, ensure compliance with local regulations and accessibility standards for pedestrians and vehicles. Lastly, evaluate the aesthetics and architectural context, so bollards integrate seamlessly into the landscape. By considering these factors, you can confidently choose the ideal height and diameter for your bollards, ensuring safety, functionality, and visual appeal.
