Determining Square Footage

Square footage is the basis of how much paint is needed for painting your basement ceiling.

To determine how much square foot is the surface area to be painted, simply multiply the length of the basement ceiling by its width. The answer would give you the paintable area by square feet. This calculation applies to a flat ceiling surface.

On the other hand, sloping ceilings form a triangular space. To determine its square footage, multiply the length or the height of the triangle by the length of its base and divide by 2. The answer is the area by square feet of one sloped ceiling. 

After computing for the area by square feet, divide the figure by 350 which is the square-foot coverage per gallon. The answer would determine how many gallons of paint you need. This calculation only applies to a single coat. Double the figure if two coats are needed.

Number Of Coats and Paint Color

The number of coats and paint color will affect how much paint you need in this basement ceiling painting project.

The double coating is the standard assuming that a primer is used. The quality and color of the paint will also determine how much coating is needed.

When a dark color paint is used, a color tint should be added to the white primer. It would be best if the tint shade chosen is close to the top coating.

With the many color choices available on the market, you may wonder what would be the best color for an exposed basement ceiling. The popular choices would be white, black, and gray. Let’s explore in detail each of these choices.


Theoretically, white is defined as the presence of all colors. It could be your first choice for an exposed basement ceiling since it is capable to augment the amount of light coming into the basement.


  • Recommended if your basement is too dark since the color can reflect more light into the interior.
  • Gives you more flexibility to play around with color.
  • Magnifies bright colors throughout your basement or even the whole house.


  • Requires more coating which translates to more painting time and costs.
  • Recommended if there are flaws in the ceiling that you intend to hide.
  • Requires a special primer in order to preserve the glow of white color over time. 


At first thought, black paint for your basement ceiling will make your space too dark. However, the black color can offer a lot of perks.


  • Can be nicely matched with light hue paint for the basement walls - It makes your basement feel cozy and restful for the eyes.
  • Helps to blend the ceiling components together - The beams, electrical, and ducts may look inconspicuous even though they are exposed.
  • Flaws at the ceiling can be concealed discreetly, which is common in old houses - The color transition between wires and pipes can be smoothly blended, giving the space a sleek appearance.
  • Reflects an artistic perspective - Black color would allow other colors in the space to be enhanced to pop out. You may complement the black ceiling with bright-colored furniture and wall paintings.


  • Dust and cobwebs stand out against a black ceiling - It requires frequent cleaning.
  • It can be laborious if you decide to redo the black paint into other colors at a later time during maintenance and basement remodeling.
  • The ceiling projects a low visual height or low vertical clearance. Much more if the basement has much less light that comes in and low ventilation—everything would appear too dark.
  • With a visually low ceiling, your basement would also give an impression of being too small in terms of area, a creepy atmosphere, and may not look encouraging to be considered for a living space. 


The gray color is a cross between black and white. It makes an excellent compromise if you cannot decide between the two colors. Gray is lighter than black, yet more subtle compared to the brightness of white.


  • Better coverage compared to white paint, which means less coating to be used - It shortens the painting time while it conceals ceiling flaws. It may be perfect for dark basements. The gray color can brighten the dark atmosphere.
  • Gives you flexibility and art since you have many options in terms of shade and hue - You can opt to mix it with other paint colors in order to achieve the color of your choice. Feel artsy and choose the appropriate shade that would boost your rather dark and drab basement.


  • The basement ceiling may look too formal or corporate as the color connotes. It’s time to enliven your artistic side and choose the appropriate furniture and fixture that could still give your basement a cozy and not-so-formal feel.
