Help Calculating Carpet Area nNeded for Stairs & Landing?

Postby MrVimes » Sat Mar 14, 2020 8:41 am

As the title suggests I need help calculating the size of carpet needed for the fitters to carpet a first floor landing and stairs.
The top landing measures at 179 x 207cm (inclusive of the drop onto the first step). then there are two steps down onto a small mid-landing that measures at 78 x 99cm (again inc. of the drop). There are ten steps down before a bullnose step at the bottom, the width of this being 79.5cm and the wrap around at 90cm.
All the steps are 75cm wide and the tread & risers measure at 41cm.
Please can someone help - I've added an image to illustrate?

Hi MrVimes,
If you are getting fitters in I would strongly recommend you leave measuring the carpet to them.
If you still want to calculate the carpet needed, get some squared graph paper, cut out the sizes you have shown and try arranging them on a piece the appropriate width.
You should end up with 5 rectangles although the stair rectangle could be cut into two. Don't forget you must allow for the lay of the carpet and any out of square floors.
