Let’s just say a home is where the heart is and my job as an interior designer has made it more rewarding for me to make every part of my clients’ home a dream come true. However, to make sure my clients dream does not turn into a nightmare, it is expedient to get measurements right as it the key element of every project in home decor. Today’s blog post will be about a very significant aspect of interior design, which is space measurement.


As an interior designer, you may not be the one taking measurements at all time. Your artisan may do that for you. But as a professional interior designer, accuracy is crucial and you are expected to measure everything. Measurement are normally done in inches—to the nearest sixteenth for window treatments and the nearest eighth for everything else—before converting them to feet as needed or required. Let’s take a look at how you need to measure a room.


Before diving into the measurement details, below is a list of important measurement aspect that you have to take into consideration when working on a project:


  • Measuring Entries and Passages
  • Measuring the Ceilings
  • Measuring the Room’s Perimeter
  • Measuring the Wall Surface
  • Measuring the Floor
  • Window Measurements
  • Furniture Measurements


I will be discussing two measuring types out of these examples I have listed above.


Measuring Entries and Passages: One major challenge we have when it comes to entrance is the size of your furniture (I mean that furniture from a top furniture company). It is very important to get accurate measurements for entries and passages because your furniture will have to pass through to get to where you have planned to place them.


After the lockdown, during COVID, I got a project to furnish a client’s house and to my greatest surprise the furniture he ordered were bigger than the entrance to the building hence it became challenging to move in the furniture. This would have led to loosing that project, but as the CEO of the top interior design school in Lagos, Nigeria with over a decade experience in the interior design Industry, I was able to maneuver and complete the project with some of my key measurement strategies.

Measuring the Room Perimeter: The idea around measuring room perimeter has to do with focusing on the overall length and width of a room. Some interior design school will tell you it is your artisan’s duty to take measurements, but you need to understand every detail of your project so as to deliver with the highest level of professionalism. Measure each wall from corner to corner, noting the size and placement of architectural elements such as doors, windows, fireplaces and staircases. Note the size and location of vents, radiators and electrical outlets as well. For irregular shaped rooms, you need to be careful. If the room you are measuring is not a square or rectangular room, you will need to measure each individual side of the room’s perimeter. Work your way around the room’s perimeter with a measuring tape, recording the length of each side of the room. In conclusion also note that in measuring room space, don’t forget to take these areas into consideration: measure the overall length and width of each room to calculate the necessary amounts of baseboard and cornice moldings, flooring materials and ceiling paint.
