The size of a pole sander can vary, depending on the individual model and manufacturer, in addition to the type of sander head being used.
Handle
Pole sander handles are available in a range of different lengths. A user can choose from one as short as 400mm (16″ approx.), or one as long as 3m (118″ approx.).
Telescopic handles can extend or shorten to suit the task in hand. Handles with this feature can usually shorten to 400mm (16″ approx.) and then extend anything up to 1300mm (51″ approx.).
Sander head
It is important to know the size of the sander head, in order to cut the piece of sandpaper to the correct dimensions.
Rectangular
A rectangular sander head is generally 80mm (3″ approx.) in width by 230mm (9″ approx.) in length, although this can be slightly different on various models.
If a user does not wish to cut sandpaper to size themselves, some rectangular sander heads will accept pre-cut sheets, which will save time as they are already the correct size.
Circular
A circular sander head is usually 230mm (9″ approx.) in diameter.
Pre-cut circular sandpaper sheets are also available for circular sander heads. These sheets are ideal, as the user does not have to waste excess sandpaper by cutting a square piece into a circular shape. They are commonly attached to the sander head via a hook and loop design, meaning there is no need for additional length to wrap around the edges.
Triangular
A triangular sander head can vary in size slightly, however, it is usually equilateral at around 240mm (9.5″ approx.) in length on each side.
Similarly to the other types of sander head, pre-cut sheets of sandpaper are available to fit most models of the triangular shape. As with the circular sandpaper sheets, they are usually attached to the sander head by a hook and loop design.
