Reading a floor plan with dimensions is an important skill to have when you are designing or building a home, or even when you are simply trying to visualize the layout of a space. Whether you are working with a simple sketch or a detailed architectural drawing, understanding how to read and interpret floor plans can help you make informed decisions about the layout and function of a space of your dream house. Without further ado, let’s start how to read a floor plan?
But, it’s important to understand about floor plan first – So:

What is a Floor Plan?

A floor plan is a detailed drawing of a room or building, showing the relationships between rooms, spaces, and other architectural features at one level. It typically includes a scale drawing of the walls, doors, windows, and other features, as well as any appliances or fixtures. Floor plans are used in a variety of contexts, including architecture, interior design, and real estate. They can be used to plan and design new construction projects, to visualize and understand the layout of a space, or to communicate design ideas to clients or contractors. Floor plans can be created by hand or using computer-aided design (CAD) software.

How to Read a Floor Plan with Dimensions

Familiarize with Basic Symbols

To begin, it’s important to familiarize yourself with the various symbols and conventions that are commonly used on floor plans. These symbols represent different architectural elements such as doors, windows, walls, sill height, clear height, floor levels, appliances, and more. For example

  • A solid line with two short dashes on one end typically indicates a wall,
  • While a dotted line may represent a non-load bearing partition!

Understanding these symbols will help you interpret the layout and understand the relationships between different elements in the space.

How to Read Dimensions on the Floor Plan

Next, you’ll need to understand how to read the dimensions on the floor plan. Dimensions are usually shown in feet and inches and are represented by a series of numbers connected by a straight line. For example,

A dimension of “10′-0” means that the element being measured is ten feet long.
When reading dimensions, it’s important to pay attention to the scale of the floor plan. Some floor plans may be drawn to a larger or smaller scale than others, which can affect the overall size.

Here are some steps to follow when reading dimensions on a floor plan:

  • Identify the element being measured, such as a wall, door, or window.
  • Locate the dimension line connecting the element to the measurement.
  • Read the measurement from left to right, starting with the number on the left. This number represents the number of feet.
  • Look for the symbol representing feet, which is usually a double quotation mark (‘) or the abbreviation “ft.”
  • The number on the right side of the symbol represents the number of inches.
  • Add the number of feet and inches together to find the total measurement. For example, a measurement of “10′-0” is equivalent to 10 feet, or 0 inches.
  • Repeat this process for each dimension on the floor plan to get a complete understanding of the layout and size of the space.

It’s important to note that different floor plans may use different symbols and conventions, so it’s a good idea to familiarize yourself with the specific conventions used on the plan you are working with.

Start Analyzing Your Floor Plan

Once you have a basic understanding of the symbols and dimensions on the floor plan, you can start to analyze the layout of the space. Look for areas that are designated as living spaces, such as the living room, kitchen, and bedrooms. These spaces will usually be larger and more open, with fewer walls and partitions. Look for the location of doors, windows, and other openings, as these can impact the flow of traffic and the overall functionality of the space.

Pay Attention to Appliances & Fixtures

You should also pay attention to the location of appliances and fixtures, such as the kitchen sink, stove, and bathroom sink. These elements should be located in convenient and logical locations, and you should consider how they will be used in relation to other elements in the space.

For example, the kitchen sink should be located near the refrigerator and stove for easy access.
In addition to the layout and functionality of the space, it’s important to consider the aesthetic aspects of the floor plan as well. Look for elements such as built-in shelving, fireplace mantels, and other decorative elements that can add character and interest to the space. Consider the overall style and theme of the space, and think about how you can incorporate these elements into your design.


Overall, reading a floor plan with dimensions requires a combination of attention to detail and creativity. By understanding the symbols, dimensions, and layout of the space, you can create a functional and visually appealing design that meets the needs of your home or project.
