From what I’ve seen, painting a room almost always takes longer than people expect. On average, you’re looking at about one to two days, but the actual time depends on several key factors—like the size of the room, how much prep work is involved, the type of paint you’re using, and whether it’s being done by a pro or someone trying it for the first time.
In this article, I’ll walk you through what really goes into painting a room. We’ll compare how long professionals usually take versus the time you should plan for if you’re doing it yourself. I’ll also break down each step of the process and highlight the main things that can speed you up or slow you down so you know exactly what to expect.
Quick Answer: Average Time to Paint a Room
For a regular-sized bedroom (about 12×12 feet with standard ceilings):
- Professionals usually finish in 6 to 10 hours, including prep, painting, and cleanup.
- DIY painters often need 10 to 16 hours, especially if it’s their first try.
- Small projects like an accent wall can be done in just a few hours.
- Bigger or more detailed rooms may take up to two full days.
Step-by-Step Breakdown of the Painting Process
Painting a room isn’t just about opening a can of paint and rolling it on the wall. There are a few steps that make the job look neat and last longer. Here’s what the process usually looks like:
1. Preparation (2–3+ hours)
Before you even touch a brush, you need to get the room ready. This means moving furniture out of the way, covering the floor with drop cloths, removing wall hangings or switch plates, fixing small holes or dents, sanding rough spots, and putting tape around trim or edges. Good prep work can take a couple of hours but saves you time later.
2. Painting (4–6 hours)
Once the room is ready, the painting starts. Most people begin with the ceiling, then move to the walls, and finally finish with the trim. Cutting in (painting carefully along the edges) takes patience, and then rolling the paint on goes a bit faster. Most rooms need at least two coats of paint for even coverage.
3. Drying Time (2–4 hours between coats)
After the first coat, you have to let the paint dry before adding the second. Latex paints usually dry in about 2-4 hours, but oil-based paints can take longer. This drying time is important if you want a smooth finish.
4. Clean-Up (1-2 hours)
When the painting is done, there’s still cleanup to think about. This includes pulling off the painter’s tape, cleaning brushes and rollers, and putting furniture back where it belongs. Cleanup usually takes another hour or two.

Factors That Influence How Long Painting Takes
Not every room takes the same amount of time to paint. A few key things can make the job go faster or slow it down:
1. Room Size and Ceiling Height
A small bedroom is much quicker to paint than a big living room with tall ceilings. The more wall space, the more time you’ll spend painting.
2. Wall Condition
If the walls are in rough shape with cracks, dents, or peeling paint, you’ll need extra prep time. Filling, sanding, and priming all add hours to the job.
3. Number of Coats
Painting a light color over another light color might only need two coats. But if you’re covering a dark wall with a bright new shade, it could take three or more coats to look even.
4. Type of Paint
Latex paints dry quickly, letting you wrap up your project faster. Oil-based paints, on the other hand, have a slower drying time, which can make the entire process take longer.
5. Experience Level
Professionals have the skills and tools to move quickly while keeping the finish neat. A DIY painter, especially a beginner, may need more time to get everything right.
6. Tools Used
The right tools make a big difference. Rollers and paint sprayers cover large areas faster than brushes, while brushes are better for small details but take longer.
Professional vs DIY Timelines
How long it takes to paint a room also depends on who’s doing the job.
Professionals
Painters who do this every day can move quickly without cutting corners. For example:
- A small room (like a home office) might take 4-6 hours.
- A medium room (like a kitchen or living room) usually takes 6-8 hours.
- A large or open-plan space can take a full day or even longer.
DIY Painters
If you decide to paint yourself, remember it will probably take more time. New painters usually need around 10-16 hours to finish a normal-sized bedroom because getting ready, painting the edges, and tidying up can be slow. However, lots of people like the feeling of doing it themselves, and it can save you money since you won’t have to pay someone else to do the work.

Special Cases
Sometimes painting a room is faster or slower than the average timeline. Here are a few examples:
Accent Walls
Painting a single wall for a colorful accent is often quick. You can often get it done in a few hours since there’s not much area to paint.
Textured or Damaged Walls
Walls with heavy texture, cracks, or water damage take longer. You’ll need extra prep work, more paint, and sometimes extra coats to get an even finish.
Big Color Changes
Switching from a dark color to a light one (or the other way around) can add time. It often takes several coats or a layer of primer to make the new color look right.
Repainting Similar Colors
If you’re simply touching up a wall with the same color or one almost the same, it’s a faster task; you might only need a single layer.
Tips to Save Time
Painting doesn’t have to take forever. With a little planning, you can finish the job faster while still making it look great. Here are some simple tips:
1. Prep Smart
Group your prep tasks together. For example, move all the furniture, then tape everything at once instead of going back and forth.
2. Use Quality Tools
Using better rollers, brushes, and tape can cost a little extra, but they help you paint faster and get a nicer result.
3. Pick Quick-Dry Paints
Latex or “fast-dry” paints help you move from the first coat to the second coat faster, cutting hours off the project.
4. Work With a Partner
Working together helps finish the task faster. One person can do the outlines, while the other paints the bigger areas.
5. Stay Organized
Keep your brushes, rollers, and paint tray nearby so you don’t waste time looking for tools while you work.
