Options For Paint Can Sizes

If you are now very knowledgeable about the common sizes of paint cans, you might find it rather difficult for yourself to define what size is standard and what size is big.

So let us explain a bit more about the standard sizes of paint cans that can be found on the market these days.

Typically, the majority of paint cans are available in a wide variety of sizes.

The most widespread (and the most popular sizes among the customers) are one pint, one quart, and one-gallon cans.

These are the ones that we can find in all the hardware stores. However, those are not the only ones you will find, of course!

For example, paint is also available in five-gallon buckets.

This option may be ideal for larger projects, for example, if you need to paint your walls. If you just want to sample the chosen color in order to see if you like it or not, you don’t need that big tank of paint for sure!

In this case, you can get a quarter-pint which is absolutely enough.

There are also intermediate sizes of paint cans. Those include half-pints and half-gallons.

As a result, by choosing the right mix of paint cans, you can usually get the precise amount of paint needed for a project you are up to without paying for too much excess, as well as without ending up with a lot of extra paint that you don’t need right now.

What Are the Standard Paint Can Dimensions?

Since now you know a bit more about the standard sizes of the paint cans, you might be wondering, what their dimensions are.

At this point, you should know that most paint cans have rather specific and individual dimensions based on their size.

However, there are several reasons why our paint cans have certain standardized dimensions.

This is done in order to ensure the paint availability and affordability, as well as make sure that it will fit in typical mixing machines.

As you all surely know, the shape of paint cans is usually a cylinder. As a result, the main dimensions most people need to know are the height and the diameter of the can.

Like this, you will know how much paint the can contains and how many cans you might need for your particular painting project.

Of course, it should be noted that smaller cans of paint have almost no distinction between the two measurements, the height and diameter. Often, this difference is non-existent, especially with half-pint cans.

The dimensions for that size of cans are approximately 2 7/8” x 2 7/8”. However, if we take a look at larger cans of paint, we will see that the difference between the dimensions tends to increase slowly.

It causes the height to exceed the diameter in greater amounts as the size of the paint can go up.

For the one pint can, for example, you end up with dimensions approximately 3 7/16” x 3 15/16”. When you take a quart-sized can, it will be closer to 4 ¼” x 4 7/8”.

One-gallon can dimensions are near 6 ½” x 7 ½”. And a five-gallon can of paint usually has dimensions of 12” x 14 ½”.

So, now you know a bit more about the tin paint can sizes.

Hopefully, this information will help you when you decide to go shopping for some interior or exterior paint for yourself to refresh your home a bit!

Anyway, this is something that is always good to know just in case.

And now that we have explained the paint cans dimensions and sizes, let’s move on and take a closer look at their coverage abilities and other characteristics that might be handy for you in future.

How Much Does One Can of Paint Cover?

This is the question that people often ask when the time comes to buy paint for their home renovation projects. How many cans of paint shall I buy in order to cover the object or the surface I need?

As you probably understand, paint cans of different sizes contain distinct amounts of paint. As a result, that paint can be used for covering different size surfaces.

If you can calculate (at least approximately) how much area each size paint can cover, it means that you can estimate the amount of paint you will need for your project.

At this point, we want you to realize that the information you get in this case is anyway estimated. The precise coverage level will depend on several essential factors besides the paint can size.

For example, it also matters how thick the layer of paint that you apply, and how heavily you apply it onto the surface.

By the way, the surface texture may also play a significant role: the more textured it is, the more paint it requires to be properly covered.

This is why in the majority of cases, you will want to use a bit more paint than you assume your project will take.

This will give you room in case you make a mistake or there is an error and you need extra paint for touch ups.

Below, we have collected the information on how much surface each type of paint can is able to cover.

Like this, you will be able to previously calculate how many cans you might need.

How much space does CAN cover? (Different CANS VS CAPS)How much space does CAN cover? (Different CANS VS CAPS)

Half Pint Paint Can

A half-pint can of paint is able to cover up to 25 square feet. Of course, that won’t be enough if you need to cover a typical wall in a house, for example.

However, a half-pint tank of paint might be exactly enough for painting one not too big furniture piece or the baseboards and crown molding in a room.

By the way, you can also use it for painting wall alcoves or niches since those don’t take much space.

Naturally, a half pint can of paint will suit all similar small projects.

Pint Can Of Paint

With a pint sized can, you can cover up to 50 square feet of any surface.

If you have an 8’ ceiling, it might be possible to cover a wall up to 6’ wide with a pint. However, in this case, you need to realize that you wouldn’t have much room for errors or mistakes.

In addition, a pint of paint might be enough for a ceiling in a small room or work pretty well for a furniture piece or two.

Quart Can Of Paint

With one quart of paint, you can cover up to 100 square feet of surface. A pint could give you enough for a larger accent wall or ceiling in a room, for example, depending on its size.

With a quart sized can of paint, it is potentially an option to paint several furniture pieces as well.

Half Gallon Can Of Paint

With a half-gallon of paint, you can usually cover up to 200 square feet.

That may be enough for painting one or even two accent walls in a room, a couple of ceilings, or a ceiling and a closet.

When it comes to furniture, you will hardly be able to paint an entire dining or bedroom set though.

In some cases, you may even have enough left over for other painting projects, too.

Gallon Paint Can

One gallon of paint will typically cover up to 400 square feet. That means that at this point, handling entire rooms is possible. In most cases, that amount of paint is more than enough for covering the walls of a bathroom, pantry, laundry, or home office easily.

It may also be enough for you to cover the ceiling depending on the room size.

In some cases, one gallon of paint might even be enough for painting a small bedroom, though it would probably only handle the walls at most!

5 Gallon Can

With a five-gallon paint can at your disposal, you can typically cover up to 2,000 square feet.

And since the average room usually requires around two gallons, it may be possible for you to paint two full rooms with that amount of paint with no effort.

Sometimes, with five gallons of paint, you can even paint an open concept living area.

However, you will anyway want to do the calculations in advance in order to confirm, as home sizes do vary quite significantly.

Spray Paint Sizes

Those of you who decide to use spray paints instead of the canned paints, might be wondering whether or not there is any difference in spray paint can sizes.

Below, we have prepared some useful information for you on this subject.

4 ½ Oz

In most cases, 4 ½ oz. can of spray paint is able to cover up to seven square feet of surface.

For example, that amount of paint may cover a small furniture piece or even two, like a dining chair or a pair of very basic stools.

Often, buying his spray paint can size is a good option if you want to add accents to several furniture pieces.

For example, you may cover just the tops of a few side tables, or only the legs of a small dining table.

Spray Paint Sizes 4 ½ Oz

12 Oz

With the 12 oz. size, the spray paint tank may be used for covering for up to twenty square feet.

That could handle either multiple small furniture pieces or one medium size one.

In some cases, a 12 oz. can of spray paint could cover the top of a dining table.

However, that would depend on the exact size, as some table tops are larger than 20 square feet.

16 Oz

Typically, a 16 oz. spray paint can covers up to 30 square feet.

That may handle one larger furniture piece or more than one medium-sized piece.

For example, you may be able to paint a pair of Adirondack chairs or one average-sized dining room table.

Like this, you are now aware of the basic distinctions in cans of spray paints and regular tin canned paints.

Hopefully, this information will help you to make the right choice when you need to decide what amount of paint is required for exactly your project.

How to Define How Much Paint I Need For My Project?

Of course, being aware of how much each paint can size contains and covers is helpful.

However, it is only a starting point of your painting job.

You will also want to calculate how much paint you might need for your project so that you get enough per one painting session.

So grab a few recommendations that we have prepared for you, and take a look at how to figure out how much paint you will need.

How to Define How Much Paint I Need For My Project

Traditional Paint

With traditional paint, it is pretty easy to figure out your paint needs.

Usually, the easiest way to do it is to calculate the amount of square footage you need to cover and then divide this number by the coverage offered by a standard paint can size.

  • Calculating the square footage for a wall is straightforward. You simply multiply the length by the height.
  • For a ceiling, you multiply the length by the width.
  • For furniture or other items, it may depend on the features of the piece. For example, with a bookshelf, you will have to include both the main structure and also the exposed surface area of all the shelves.

For dressers, it is going to be a bit different. You need to define how many drawers you want to paint. Just multiply the height, width, and length of the piece for the beginning.

Then, if you don’t plan to paint the back, multiply the height and width of the piece and subtract that from the previous total.

But basically, no matter what object exactly you need to paint, once you have the surface, you can divide it by 400 to see how many gallons of paint you’ll need.

However, it’s usually best to round up.

As mentioned above, one gallon of paint can cover up to 400 square feet, so it isn’t guaranteed to stretch that far.

As a result, you may want to anticipate needing more than the math suggests, just to be safe.

Spray Paint

Estimating your paint needs for spray paint isn’t much different from the method we described above.

You just don’t base your calculation on the coverage offered by one gallon of paint.

Instead, you do the calculations based on the can size that will be used.

  • Start by choosing a hue and seeing what sizes are available.
  • Then, use the process described above in order to calculate the amount of square footage you want to cover.
  • Once you have the square footage, simply divide that number by the coverage amount offered by your spray paint can size, rounding up to give you some room for error.

What Size Of Surface Can One Gallon Of Paint Cover?

One gallon of paint can cover up to 400 square feet. However, the exact amount of the surface covered can vary depending on a few factors.

  • The thickness of the paint. Thicker paint covers less area than a thinner one.
  • Wall texture. A highly textured wall has more nooks and crannies on the surface. As a result, there’s more area to cover than with a smooth wall, so it can take more paint.

Since 400 square feet is considered to be the upper limit, it is usually best to slightly overestimate your paint needs and get some extra.

In some cases, simply rounding up after dividing the area by 400 is enough to give you some room for error.

However, if the original calculation came out close to a whole number, then you may want to buy an extra paint can as a precaution.

How Much Paint Is Needed Per One Square Foot?

If you are curious about how much paint it takes to cover a single square foot of a surface, it usually appears to be a little less than two teaspoons. Overall, there are about 768 teaspoons in a gallon.

Since one gallon of paint covers up to 400 square feet, 1.92 teaspoons can handle up to 1 square foot.

Just to compare these data, check out how it will look with the metric system: it works out to around 9.5 milliliters per square foot. In total, a gallon is equal to about 3785 milliliters.

If you divide that by 400 square feet, you get a little less than 9.5 milliliters per square foot.

Still, that isn’t usually an ideal way to estimate your paint needs.

However, since you are limited to specific paint can sizes, it is typically better to use their associated coverage amounts as a baseline.
