Painting a room is a time-consuming and physically demanding project, but knowing how much paint to buy can save you money and multiple trips to the store. The amount of paint needed for a large bedroom depends on the dimensions of the room, the surface texture of the walls, the type of paint, and the number of coats. Paint calculators can be used to determine the exact amount of paint needed, but a typical rule of thumb is one gallon for about every 300 to 400 square feet. For a large bedroom with 800 square feet, two gallons of paint will be needed for one coat, and four gallons for two coats. If you are painting over a dark colour with a lighter one, you may need up to three coats.

What You'll Learn
Paint calculator
The amount of paint you need for a large bedroom depends on several factors, including the dimensions of the room, the paint brand, the paint type, and the number of coats you plan to apply.
Room Dimensions
To estimate the amount of paint needed, you must first measure the length, width, and height of your room. Don't forget to account for doors, windows, and moulding, as these areas won't require paint. Including these in your calculations will help you avoid buying too much paint.
Paint Brand and Type
Different paint brands and types have varying coverage capabilities. Generally, paint is applied at 350 to 400 square feet per gallon, but this can differ based on the specific paint brand and type. For instance, high-gloss paints may provide more coverage per gallon compared to flat paints, which are more absorbent. Specialty paints, such as those designed for high-moisture areas or those with primer mixed in, may also require different amounts.
Number of Coats
The number of coats you intend to apply will also impact the amount of paint needed. If you're applying multiple coats, you'll need to double the amount of paint to accommodate the additional layers.
To make your calculations easier, you can use an online paint calculator. These tools allow you to input room dimensions, paint brand, and other relevant factors to estimate the amount of paint required.
Remember, it's always a good idea to purchase a little extra paint than calculated to ensure optimal coverage and avoid last-minute interruptions for additional paint purchases.

Paint type
The amount of paint you'll need for a large bedroom depends on the paint type, sheen, and surface texture of the walls. Generally, one gallon of paint covers about 350 to 400 square feet, but this can vary depending on the paint's formula and the wall's texture. Highly textured surfaces, for instance, may absorb more paint and require a bit more coverage. Additionally, the number of coats you intend to apply will also impact the amount of paint needed; applying multiple coats usually requires doubling the amount of paint.
Now, let's discuss paint types and how they can influence the quantity required for your large bedroom:
The type of paint you choose for your bedroom can significantly impact the amount of paint you'll need and the overall aesthetics. Here are some common types of paint sheens and their characteristics:
- Flat or Matte Paint: This type of paint has little to no sheen and reflects less light, creating a calming and relaxing atmosphere in your bedroom. It is ideal for hiding surface imperfections and is commonly used in low-impact areas like bedrooms. However, it may absorb more paint than other sheens, so you may need to consider this when calculating the amount of paint required. Flat or matte paint is a good option if you're looking for a forgiving finish that can conceal any wall flaws.
- Eggshell Paint: Eggshell paint has a lower sheen than satin and is known for its ease of cleaning. It usually falls between flat/matte and satin in terms of sheen level and can be a good option if you want something in between.
- Satin Paint: Satin paint has a medium sheen and is known for its durability and ease of cleaning. It has higher levels of resin and lower levels of pigmentation, resulting in a glossier finish. Satin paint is commonly used in bedrooms, especially if you have children, as it is more wipeable than flat or matte finishes.
- Semi-Gloss Paint: Semi-gloss paint has a higher sheen than satin and offers excellent resistance to moisture. It is commonly used in high-humidity areas like bathrooms and kitchens and high-traffic spaces. While it is easy to clean and durable, semi-gloss paint may accentuate any blemishes on walls and ceilings.
- High-Gloss Paint: High-gloss paint has a very high sheen and provides a dramatic light reflection. It is highly durable, easy to clean, and resistant to dirt, stains, mould, and mildew. However, due to its high sheen, it requires more prep work and sanding for a smooth application. High-gloss paint is an excellent choice for areas that require high durability and ease of maintenance.
When selecting a paint type, consider the desired level of sheen, the functionality of the space, and the overall aesthetic you wish to achieve. Additionally, specialty paints, such as those designed for high-moisture areas or those with primer mixed in, may also impact the quantity of paint needed. Primer-infused paints, for example, may require fewer coats, reducing the overall amount of paint needed.

Wall texture
The amount of paint needed for a large bedroom depends on several factors, including the height of the ceiling, the presence of windows and doors, and the colour you are painting over. On average, paint covers 350 to 400 square feet per gallon, but this can vary depending on the paint type and wall texture. For example, highly textured surfaces may absorb more paint, requiring a greater volume.
When it comes to wall texture, there are numerous options to consider for a bedroom:
- Skip Trowel Texture: This texture is created by applying a thin layer of joint compound with a trowel and "skipping" it across the wall, resulting in a distressed and uneven finish. This texture is well-suited for rustic and rural decor.
- Knockdown Texture: This texture is achieved by applying joint compound to the wall and then slightly flattening it with a trowel, creating a textured, stucco-like finish. It adds a rustic charm to any room and pairs well with earth tones and natural materials.
- Popcorn Texture: Also known as acoustic texture, this option was popular in the mid-20th century for its sound-dampening properties. While less common today, it is still used on ceilings to reduce noise and hide imperfections. It is important to note that this texture can be challenging to clean and repair.
- Sand Swirl Texture: This texture is made using perlite primer and sand, applied to the wall and manipulated with a thick-bristled brush to create a mesmerizing swirl pattern. It is a good option for bathrooms and kitchens as it resists damage from moisture and heavy use.
- Exposed Walls: For an industrial vibe, consider leaving walls exposed, with concrete finishes.
- Three-Dimensional Surfaces: 3D wall panels introduce depth and dimension, with raised surfaces creating an interplay of light and shadow.
- Faux Brick Textures: Brick textures provide an impressive backdrop for a bed. Brick-look tiles or wallpaper can achieve a similar effect.
- Wall Panelling: Upholstered wall panels incorporate fabric as a textural element, resulting in a warm and inviting space. They are beneficial for acoustics, contributing to an improved sleep environment.

Number of coats
The number of coats of paint you will need for a large bedroom depends on several factors, including the colour you are painting over, the colour you are using, the texture of the walls, and the quality of the paint.
If you are painting a large bedroom, you will likely need at least two coats of paint for even coverage. Applying multiple coats ensures a consistent finish and prevents the old colour from showing through. However, the number of coats can vary depending on the specific circumstances.
For example, if you are painting a light colour over a darker colour, you may need up to three coats. On the other hand, if you are painting a dark colour over a light colour, you may be able to get away with one coat. Additionally, keep in mind that highly textured surfaces may absorb more paint, requiring more coats compared to smooth surfaces.
To calculate the exact number of coats needed, you can use a paint calculator. These calculators consider factors such as the square footage of the walls, the number of doors and windows, and the coverage area of the paint. By inputting these values, you can determine the precise number of coats required for your large bedroom.
It is always advisable to purchase a little extra paint than calculated to account for any unforeseen circumstances or touch-ups. Planning ahead and considering these factors will ensure a smooth and efficient painting process for your large bedroom.

Room dimensions
The amount of paint needed for a room depends on the dimensions of the room, the number of coats, the colour of the paint, the type of paint, and the surface texture of the walls.
A gallon of paint typically covers around 350 to 400 square feet of wall space. To calculate the amount of paint needed, you need to measure the length and height of each wall and multiply them to get the square footage. Add the square footage of each wall together to get the total square footage of the room. Subtract the size of any windows and doors in the room.
If you plan to apply multiple coats, you will need to double the amount of paint. For example, a room with 400 square feet of wall space will require one gallon of paint for one coat or two gallons for two coats.
If you are painting over a dark colour with a lighter colour, you may need up to three coats. Primer-infused paints may require fewer coats, reducing the overall amount of paint needed.
For a large bedroom, the amount of paint needed will depend on the specific dimensions of the room and the number of coats you plan to apply. As a rough estimate, an average-sized bedroom of around 800 square feet will typically require two gallons of paint for two coats.
It is always a good idea to purchase a little extra paint to account for wastage and to ensure optimal coverage.
