Designing a Pergola
Pergolas comprise of three parts; support posts, main beams and top beams. The timber
specifications are dependant on the purpose, size and positioning of the pergola.
When designing larger pergolas we recommend using 125 x 125mm posts. This allows
adequate room for a 50mm notch in the top of the post.
The main beams are generally 47 x 125mm or 47 x 150mm depending on the span and can
be ‘S’ shaped at the ends. For example, 47 x 125mm for up to a 3.6m span and 47 x 150mm
for a 4.8m span (guide purpose only).
Top beams can also have ‘S’ shaped ends and be notched to sit onto the main beam at
approximately 600mm centres. However all this depends on the size of the pergola and the
look and feel you are trying to create with your design.
The size of the timber used is important so the structure is not only safe but also creates the
right balance of timber to compliment its surroundings.
