**Calculating Space Needs and Setting the flatness of the Stairs **| Laying down the stairs as a liaison between floors vertically just take up space. So that no wasted space, the space requirement for the ladder should be calculated in detail.

Mathematically the needs of the staircase can be calculated by finding the length of the ladder are affected by the height between floors, the height of the stairs, and stair widths.

The formula to calculate the length of the ladder is as follows

The length of ladder = (H / t) x L

H is the difference in height between the floor, t is the height of the planned steps, and L is the width of the stairs.

If the length of the ladder is found, adjust the room is, if the length of the ladder is in accordance with the size of the room or not. If not, then you can be fiddling with the shape of the stairs so long enough.

**Set the flatness of the Stairs**

*Leisure walking up the steps is determined from the slope*. The size of the slope affected by the height and width of the stairs. The stairs are steep if the height of the stair. Similarly, if the width of the stairs that slope of the stair. The ideal height of steps ranging from 14 cm – 22 cm and width of stairs 20 cm – 33 cm.

To make it easier to calculate the height and width of the stairs right there is the formula 2a + b = 63 cm, where a is the height of the steps and b is the width of the stairs.

Steep stairs when 2a + b + b> 65 cm. While the sloping stairs if 2a + b <60.

Actually, the ladder has the advantage that it saves steep stairwell. But from the side away from the expected comfort. When climbing the stairs, the foot was sore because the steps are too high. In addition to discomfort, such as the stairs are dangerous for small children and the elderly.

Room with a ladder to adjust the length of the ladder. If the form of a straight ladder is not possible with a certain length of the ladder can be shaped L.

Ramps of **stairs that provide comfort**. However, the staircase is required is also not small.
