A floor plan depicts each floor of a structure from the perspective of a bird’s eye view as if there were no roof and only a few fundamental structural elements such as walls and doors. Because stair shorthand and symbols are ubiquitous in architectural floor plans, drawing them is a basic and straightforward operation.

The most difficult challenges are drawing to scale, using the proper stair measures, and deciding where the steps should go.

On the exterior of a structure, stairwells, ramps, elevators, and escalators allow access to different floor levels. In buildings of more than two stories or less, stairwells and ramps are commonly used, whereas elevators and escalators are used in taller structures.

What Are Stairways Dimensions?

The landing sizes, widths, and runs of each stair are dimensions on the floor drawings. The plan also shows the overall number and dimensions of the risers and runners. The stair risers’ vertical heights, railings, and other details are dimensioned on a separate section or elevation drawing cross-referenced to the plan.

Depending on the number of components and the size and complexity of the construction, the stair materials can be indicated in various ways.

The structural materials beneath the surface may be noted or shown in a sectional view. This should be stated if the structural material is also the finished surface. If the stair is covered in a different finish material, it may be indicated in the section view, plan view, or a separate finish sheet.

Draw Stairs According To Their Designs

Making one design choice triggers what seems like a million additional tasks. Concerning your stairs, that is unquestionably accurate. The blueprints may have been penciled with it, but that is only the beginning. The staircase’s physical shape is the first item you should consider.

Bring your top choices so your architect and builder can discuss what might work best for your house.

  • L-shaped stairs
  • winder stairs
  • U-shaped stairs
  • spiral stairs

  • ladder stairs

Steps To Draw Stairs

Gather Your Supplies

  • pencil
  • ruler
  • a paper
  • drawing accessories
  • speed square
  • sharpener
  • eraser

1) Consider The Stairs Layout

Choose a location in the floor layout for the stairs. Consider the building’s layout and where it’s easiest to transition between floors. Calculate how far the stairwell must travel to reach the because the risers and treads of the stairs are always the same height and width.

Moreover, the stairs must be comfortable to go up or down; this action plays a significant part in defining the length of the steps.

2) Determine The Stair’s Length According To The chosen Scale

Convert the length of your stairwell to the scale you’re using for your floor plan. 12-foot stairs would be 3 inches long if 1/4 inch on the drawing equals 1 foot in real life.

Determine The Stair's Length

It is a standard scale for blueprints. To build the stairway, draw a rectangle with the appropriate scaled dimensions. Draw an arrow parallel to the rectangle’s long side and within the rectangle.

In the building, point the arrow in the direction of the stairwell. The arrow always points up the steps from the bottom.

3) Draw Treads And Diagonal Lines

 Draw Treads And Diagonal Lines

Divide the rectangle into sections with parallel lines. Draw around seven treads, then divide the rectangle with a diagonal line that cuts through several treads. Draw a jagged line into the diagonal to look like a seismograph reading. This is a shorthand approach for drawing steps in a floor design representing a stairwell.

4) Repeat The Same Steps

To make circular stairs, repeat the steps above. Instead of creating a rectangle with your compass, draw a circle with your compass and use your architect’s rectangle to design the treads that resemble pie slices in a circular staircase.

How To Figure Out The Stairs?

  • Calculate the total number of steps required. The height of the space is divided by the height of each step, assuming an ideal riser of 15-18 cm.
  • Determine the height of each of the risers.
  • Determine the tread’s breadth.

Stairs Drawing In An AutoCAD

Select a stair tool from the tool menu you want to utilize. Scroll down if necessary to see the tool you you want to utilize.

  • Determine the stair’s insertion point.
  • Define the stair’s direction point.
  • Press Enter as you continue to construct

Solidianceid Face, Brics CAD, DraftSight and SketchUp are free alternative to AutoCAD you can use,” comments James Durr of auctioneers of property in Birmingham (UK).

What Are Draft Standards For Drawing The Stairs?

The complexity of the stair and the basic structural material it is made of determine the design and drawing details required to represent it. Wood, steel, and concrete are the most common materials used in stair systems. Wooden stairs are the most common and easiest to create and detail in residential buildings.

Stairs are labeled with their basic widths and the number of treads and risers on the floor designs. The plan includes the run and an arrow showing whether the stairs lead up or down from that level.

Consider The Adequate Details For Railings And Millwork

Cabinetry and millwork such as moldings, paneling, miscellaneous trim, and door and window casings are sometimes drawn at a scale too tiny to show considerable detail for cabinetry and millwork.

These elements are drawn in size and cross-referenced to the basic plans. Millwork and cabinetry, often known as architectural woodwork, can contain prefabricated stock components and custom woodwork produced on the project.

Although some designers classify cabinets as millwork drawings required to depict it will be considered a separate classification.

Way To Draw Stairs From Two-Perspective

Once familiar with the two-point perspective sketching technique, drawing stairs from two points of view is pretty easy. Establishing the horizon line on which the two locations will be drawn is the first step in the process. The angle at which you are looking at the steps is then established by drawing a vertical line.


You start drawing the stairway from there while using the two-point viewpoints to direct your lines. The shading procedure gives the staircase drawing a more lifelike appearance. By doing this, we will add more dimension to the staircase drawing.


A floor plan is a two-dimensional scale drawing that shows the room layout and the placement of walls, doors, and windows. Buyers and tenants can use floor plans to grasp the property’s essence, the areas, connecting points, outlooks, and flow. The accuracy of a floor plan’s scale is the most significant feature.

Like many other components of a home’s architecture, the stairs provide an opportunity to provide both useful and accessible access and an appealing and unique element that adds to the owners’ enjoyment of living in their homes.
