When it comes to measuring your new staircase it is important that you get the correct measurements , use this guide to help you understand the measurements we require to calculate your new staircase.

For a straight staircase measure your rise measurement first, this is the distance from the finished floor level where the staircase starts to the finished floor level on the upper floor where the staircase is going to. If your floors are slightly out of level the make sure you get your rise from the points where the staircase is going to sit.
Once you have your rise you can work out the going distance (Dimension G) for the stairs this is the distance the staircase will project along the floor, look at our rise and go chart to see the correct going to suit your rise height when trying to achieve a 42 degree pitch.
If you are measuring a staircase for between walls make sure you measure the narrowest point and allow a clearance, this is OK if the staircase is assembled and the staircase can slide into place without having to be turned in the hole (between the walls) and is also OK if the staircase is ordered flatpack for assembly in situ between the walls, but if your staircase is going to need turning in between the walls you need to allow more clearance normally 75mm is OK but this needs checking before ordering, to work this out you need to draw a rectangle to scale (draw a rectangle the proposed width by 244mm which is the typical depth of the stair stringers we use and measure across the furthest points to check you can rotate the staircase)
The width is also important when it comes to your landing room at the top and the bottom as this needs to be equal or more than the width of the staircase.
The width of a standard domestic staircase is 860mm over all the strings, the minimum width we would recommend for a Loft staircase is 600mm over all the strings.
If you are measuring a staircase which is to have handrails to one side and it is quite tight to the well hole you need to think about finger room between the handrail and the side of your stairwell the minimum clearance we recommend is 40mm this would mean you need to allow 55mm clearance on you over all string measurement from the finished well size.

As with straight stairs start with your rise measurement and use the rise and go chart to work out the number of risers required and the going size your treads need to be to give you a 42 degree pitch, take your going dimension G1 and work out haw many goings will fit and what width you are left with remember the width of a standard domestic staircase is 860mm, you will probable have 2 choices of rise heights to choose from eg :- 12 or 13 risers these will have different going sizes you need to choose the one that suits best, Your next size the G measurment is governed by the number of goings you need and the width of the staircase.
With a quarter landing staircase you will only need to allow the width of the staircase in the corner for your turn, with a winder staircase things get a little more complex. With the UK building regulations there are 2 important factors to remember ; -
1. Minimum 50mm Going - at the inside edge of your winder treads you must have a minimum going of 50mm, this means on a typical 860mm wide staircase with a standard 90mm newel post in the corner the typical area for a 3 tread winder corner increases by around 30mm so on a 860mm wide stair the typical winder box size is 890 x 890mm.
2. Winder Walk line Going - UK building regulations require the distance in the center of a winder tread to have a going no less than the going on the main part of the staircase, on staircases wider than 800mm Overall strings this is not normally an issue but on narrower staircases it is required to increase the winder box size by more than the 30mm as detailed above for the 50mm goings to achieve a walk line going that meets the requirements. EG - a 600mm wide staircase would need a winder box size of typically 750 x 750mm.
For Half Landing staircases and Double winder staircases you will need to check the width of the area you can fit the staircase into and also let us know if there is a restriction as to how far the staircase can come out at the bottom other than the restriction goverened by headroom from the stairwell above.
