KwikStairs - The Basics

1) Measure the lower finished floor to upper finished floor where your stairs will eventually fit. In the unfortunate case you are not able to find your lower finished floor to higher finished floor measurement, please see the technical information area further down for more information and guidance

2) Use the tread guide below to work out the number of treads you will need for your new stairs (including nosing):

Finished Lower To Higher Floor Measurement Number Of Treads (Including Nosing)
1781-1980mm 9
1981-2200mm 10
2201-2420mm 11
2421-2640mm 12
2641-2860mm 13
2861-3080mm 14 (14 or more treads must include a winder box)

3) The product images on this website are all based on a 13 tread staircase. Should your floor to floor measurement give a different number of treads, you'll need to adjust the measurements by 245mm per tread if you require more or less than 13

4) All width measurements are from the outside edge of each string

5) All length measurements are from the front face of the first riser to the trimmer or outside edge of the joining winder box, and outside edge of the winder box to the trimmer or outside edge of the joining winder box

6) You need to decide on the width of the staircase:

Options
900mm (and less) for a KwikStairs straight flight
Or 900mm, 850mm, 800mm, 750mm, 700mm, 650mm for any KwikStairs winding combination

7) Measure the space available to you for where you would like your stairs

8) Decide on the style of staircase you would like (straight flight, single winder, double winder or 'S' winder)

9) Navigate to that section of the guide below

10) Look at all the styles and measurements for your chosen width of stairs

11) Is there a style that will fit the space available to you?

KwikStairs Straight Flight Guide

If you've decided on a straight flight set of KwikStairs for your home, please use the below guide to work out the width and length of your new stairs. Please be aware that when constructing straight flights only, KwikStairs can be made at any width up to 900mm wide. The below straight flight measurement key is based on a 13 tread staircase (floor to floor 2641-2860mm).

A Measurement (width of current stairs = horizontal dimension of new stairs) B Measurement (width of current stairs = width of new stairs)
900mm = 2950mm 900mm = 900mm
850mm = 2950mm 850mm = 850mm
800mm = 2950mm 800mm = 800mm
750mm = 2950mm 750mm = 750mm
700mm = 2950mm 700mm = 700mm
650mm = 2950mm 650mm = 650mm

So if you require a 900mm width staircase then: dimension A = 2950mm and dimension B = 900mm. To add or minus a tread, alter the above measurements by 245mm. Use the decision tree below to help you decide between all the different KwikStair product options:

Please be aware that when constructing straight flights only, KwikStairs can be made at any width up to 900mm wide. The below product images and measurement examples are based on a 13 tread staircase (floor to floor 2641-2860mm).

A Measurement (width of current stairs = horizontal dimension of new stairs) B Measurement (width of current stairs = width of new stairs)
900mm = 1912mm 900mm = 2167mm
850mm = 1862mm 850mm = 2117mm
800mm = 1812mm 800mm = 2067mm
750mm = 1762mm 750mm = 2017mm
700mm = 1712mm 700mm = 1967mm
650mm = 1662mm 650mm = 1917mm

So if you require a 900mm width staircase then: dimension A = 1912mm and dimension B = 2167mm. To add or minus a tread, alter the above measurements by 245mm. Use the decision tree below to help you decide between all the different KwikStair product options:


KwikStairs Right/Left Single Winder Combinations

Please be aware that when constructing straight flights only, KwikStairs can be made at any width up to 900mm wide. The below product images and measurement examples are based on a 13 tread staircase (floor to floor 2641-2860mm). We recommend that you look at the B measurement first as this descends in size.

A Measurement B Measurement C Measurement
900mm = 1667mm 900mm = 1864mm 900mm = 1677mm
850mm = 1617mm 850mm = 1764mm 850mm = 1627mm
800mm = 1567mm 800mm = 1664mm 800mm = 1577mm
750mm = 1517mm 750mm = 1564mm 750mm = 1527mm
700mm = 1467mm 700mm = 1464mm 700mm = 1477mm
650mm = 1417mm 650mm = 1364mm 650mm = 1427mm

So if you require a 900mm width staircase then: dimension A = 1667mm, dimension B = 1864mm and dimension C = 1677mm. To add or minus a tread, alter the above measurements by 245mm.

A Measurement B Measurement C Measurement
900mm = 1912mm 900mm = 1864mm 900mm = 1432mm
850mm = 1862mm 850mm = 1764mm 850mm = 1382mm
800mm = 1812mm 800mm = 1664mm 800mm = 1332mm
750mm = 1762mm 750mm = 1564mm 750mm = 1282mm

Technical Information

Domestic Stairs Calculator

-MEASURE THE LOWER FINISHED FLOOR TO UPPER FINISHED FLOOR-

     

     This is the measurement needed for the height of your
     existing staircase. From the finished surface of the floor
     where the stair (lower floor) is to start to the finished
     surface of the next floor where the stair is to end (upper
     floor).

-USE THE TREAD CALCULATOR BELOW TO WORK OUT THE NUMBER OF TREADS YOU WILL NEED INCLUDING THE NOSING-

Finished Floor To Finished Floor Measurement Number Of Treads (Including Nosing)
1781mm - 1980mm 9
1981mm - 2200mm 10
2201mm - 2420mm 11
2421mm - 2640mm 12
2641mm - 2860mm 13
2861mm - 3080mm 14

Note: 14 or more treads must include a winder box

Look for your finished floor to finished floor measurement and the table above will advise you on how many treads your staircase will require including nosing. Should you not be able to find your finished floor to finished floor measurement from above, then please use the following calculation to obtain it:

Example:
Finished floor to finished floor measurement in mm = 1590mm
Divide by 220mm = 7.22
If a partial figure, please round up to the next whole figure = 8
Total number of treads including nosing = 8

-CALCULATE THE SPACE REQUIRED FOR YOUR STAIRCASE-

    All calculations start from the lower floor and work
    upwards.

     GOING - The measurement between the front of the riser
     on the lower tread to the front of the riser on the upper
     tread (always 245mm).

     TOP RISER - This is the very last top riser fitted on site that
     the nosing sits on (always 10mm).

     Every measurement length given is always to the front face
     of the rise.

     No allowance has been made for the small 20mm bull-nose
     overhang on your bottom tread.

-WINDER BOX-

     This can either be left hand or right hand in direction. The
     kit comes in its largest form but is detailed to show six
     standard widths. Each box is aesthetically designed so that
     any adjoining straight flight meets the centre of the winder
     box newel post. Therefore every winder box is 32mm larger
     than the width of the adjoining straight flight.

Staircase Measurement Winder Measurement
650mm wide staircase = 682mm x 682mm winder box size
700mm wide staircase = 732mm x 732mm winder box size
750mm wide staircase = 782mm x 782mm winder box size
800mm wide staircase = 832mm x 832mm winder box size
850mm wide staircase = 882mm x 882mm winder box size
900mm wide staircase = 932mm x 932mm winder box size

-CALCULATING A STRAIGHT FLIGHT-

     

     Multiply the number of treads that you need by the going
     (245mm). Add that to the nosing (10mm). This shows you
     the total length of your straight flight staircase.

Example:
Floor to floor = 2660mm
Number of treads = 13 including nosing
Depth of treads 245mm = 12 x 245 = 2940mm
Depth of nosing riser 10mm = 1 x 10 = 10mm
Total length of staircase = 2940mm + 10mm = 2950mm

-CALCULATING A SINGLE WINDER-

Deduct the winder box treads (3) and the nosing (1) from your overall total treads required. This will then give you the remaining number of straight treads you require.

     Multiply the number of straight treads that you require, if
     any, before the winder box by the going (245mm).

     Obtain your chosen winder box size from the
     measurements listed in the winder box section.

     Multiply the number of straight treads that you require, if
     any, after the winder box by the going (245mm).

     Add to this the nosing (10mm).

Example 1:
Floor to floor = 2660mm
Number of treads = 13 including nosing
Tread 245mm = 4 x 245 = 980mm (4 treads)
900mm wide winder = 932mm x 932mm (3 treads)
Tread 245mm = 5 x 245mm = 1225mm (5 treads)
Nosing riser 10mm = 1 x 10 = 10mm (1 tread)
Length of staircase = 980mm + 932mm = 1912mm
Length of staircase = 932mm + 1225mm +10mm = 2167mm

To find out more details about KwikStairs, please check out the official product brochure here.

Example 1:
Floor to floor = 2660mm
Number of treads = 13 including nosing
800mm wide winder = 832mm x 832mm (3 treads)
Tread 245mm = 9 x 245mm = 2205mm (9 treads)
Nosing riser 10mm = 1 x 10 = 10mm (1 tread)
Length of staircase = 832mm = 832mm
Length of staircase = 832mm + 2205mm + 10mm = 3047mm

-CALCULATING A DOUBLE WINDER-

Deduct both the winder box treads (6) and the nosing (1) from your overall total treads required. This will then give you the remaining number of straight treads that you require. Multiply the number of straight treads that you require, if any, before the first winder box by the going (245mm).

     Obtain your chosen winder box size from the
     measurements listed in the winder box section.

     Multiply the number of straight treads that you require, if
     any, after the first winder box and before the second, by the
     going (245mm).

     Use again the same winder box size as above. Multiply the
     number of straight treads that you require, if any, after the
     second winder box, by the going (245mm). 

     Add to this the nosing (10mm).

Example 1:
Floor to floor = 2660mm
Number of treads = 13 including nosing
Tread 245mm = 2 x 245mm = 490mm (2 treads)
900mm wide winder = 932mm x 932mm (3 treads)
Tread 245mm = 3 x 245mm = 735mm (3 treads)
900mm wide winder = 932mm x 932mm (3 treads)
Tread 245mm = 1 x 245mm = 245mm (1 tread)
Nosing riser 10mm = 1 x 10 = 10mm (1 tread)
Length of staircase = 490mm + 932mm = 1422mm
Length of staircase = 932mm + 735mm + 932mm = 2599mm
Length of staircase = 932mm + 245mm + 10mm = 1187mm

-CALCULATING A DOUBLE WINDER-

Example 2:
Floor to floor = 2660mm
Number of treads = 13 including nosing
Tread 245mm = 3 x 245mm = 735mm (3 treads)
800mm wide winder = 832mm x 832mm (3 treads)
800mm wide winder = 832mm x 832mm (3 treads)
Tread 245mm = 3 x 245mm = 735mm (3 treads)
Nosing riser 10mm = 1 x 10 = 10mm (1 tread)
Length of staircase = 735mm + 832mm = 1567mm
Length of staircase = 832mm + 832mm = 1664mm
Length of staircase = 832mm + 735mm + 10mm = 1577mm

-HEAD HEIGHT-

Your staircase must always have a clearance of 2 metres from the 'pitch line' as illustrated to the left. This makes an allowance for health and safety guidelines when ascending or descending the staircase.
