Quick Answer: How Long Does Paint by Numbers Take?
- 30×40 cm kit (beginner, 24 colours): 8 to 12 hours total across 4 to 6 sessions.
- 40×50 cm kit (standard, 24 to 36 colours): 12 to 18 hours total across 6 to 9 sessions.
- 50×60 cm kit (detailed, 36 to 48 colours): 18 to 25 hours total across 9 to 13 sessions.
- 60×80 cm kit (large, 48 colours): 25 to 35 hours total across 12 to 18 sessions.
- Most people paint in 1 to 2 hour sessions, 2 to 3 times per week, finishing most standard kits within 3 to 6 weeks.
It is the first question almost everyone asks before buying a kit. You want to know whether you are signing up for a weekend project, or something that is going to sit on your table for two months. The honest answer is that completion time varies more than most people expect, and the size of the canvas is only part of the story.
Experience level matters. Colour count matters. How long you sit per session matters. Whether you are a methodical painter who lets each section dry before moving on, or someone who works section by section across the whole canvas, matters. This guide covers all of it, with realistic numbers based on real kits at every size we sell.
Completion time varies by canvas size and detail level, but most adult kits take between 8 and 30 hours spread over several sessions.
The Biggest Factor: Canvas Size
Canvas size is the single most reliable predictor of how long a kit will take. More surface area means more numbered sections to fill, more colour switching, and more time with the brush in your hand. Here is a straightforward visual breakdown of what each size actually means in practice:
Estimated Total Hours by Canvas Size
Estimates based on a confident beginner painting in 1 to 2 hour sessions. Experienced painters may work 20 to 30% faster. Highly detailed designs with many small sections add time at every size.
These estimates assume you are working through the kit properly, applying two coats where colours are thin, and not rushing to cover canvas in one sitting. If you try to finish a 60×80 cm kit in a weekend, you will likely end up with uneven coverage and visible canvas showing through where colours were not fully built up.
The Second Factor: Colour Count
Our kits come in three colour configurations: 24 colours, 36 colours, and 48 colours. This is not just about how rich the final painting looks. It directly affects how long the kit takes, in two ways.
First, more colours means more small sections. A 48 colour kit packs significantly more detail into the same canvas size as a 24 colour kit. Those extra sections are smaller, and smaller sections take more time and precision to fill cleanly. Second, more colours means more time managing your workspace. Finding the right pot from 48 options takes longer than from 24, and cleaning your brush between more distinct colours adds up across a full session.
| Colour Count | Section Size | Added Time vs 24 Colours | Best For |
|---|---|---|---|
| 24 Colours | Larger, more forgiving sections | Baseline | Beginners, first kits, relaxed painting |
| 36 Colours | Medium sections with some fine detail | Add roughly 20 to 30% | Anyone who has finished at least one kit before |
| 48 Colours | Small sections, high precision required | Add roughly 40 to 50% | Experienced painters wanting exhibition-quality results |
A 40×50 cm kit with 24 colours might take you 12 to 14 hours. The same canvas size at 48 colours could easily run 18 to 22 hours. The finished result is significantly more detailed and lifelike, but the time investment is real. If you are choosing your first kit, starting at 24 colours is the right call regardless of canvas size. Our guide to choosing between 24, 36, and 48 colours breaks down exactly what you get at each level.
What to Expect at Each Canvas Size
Canvas size is the single biggest factor in how long your kit will take. A 30×40 cm kit and a 60×80 cm kit are completely different commitments.
30×40 cm: The Starter Canvas
This is the smallest canvas size in our range, and it is an excellent starting point if you have never done paint by numbers before. The sections are larger relative to the overall canvas, which means fewer tiny areas requiring a fine brush, and more satisfying visible progress per session. Most people finish this size in 4 to 6 sessions of around 90 minutes each.
Do not mistake smaller for easier in terms of skill. A 30×40 cm design can still be quite detailed depending on the subject. A landscape with sky, water, and foreground detail will have more sections than a bold single subject like a flower or a simple animal portrait. Check the colour count before you buy, not just the canvas dimensions.

40×50 cm: The Most Popular Size
This is the size most people picture when they think of paint by numbers for adults. It is large enough to feel like a proper painting when finished, and small enough that you are not committing to weeks of work before seeing the end result. Our adult paint by numbers collection uses this canvas size as the standard, and it is the size we recommend for anyone returning to painting after a break, or anyone confident they will stick with the project through to completion.
At a steady pace of two sessions per week, most people finish a 40×50 cm kit in 3 to 4 weeks. The process is genuinely meditative once you find your rhythm. The first session often feels slow because you are figuring out your system. By the third session, most painters settle into a comfortable flow and start to enjoy the process as much as the result.
50×60 cm: The Detail Step Up
This is where the real depth of a paint by numbers painting starts to reveal itself. At 50×60 cm, the designer has room to include fine gradients, detailed backgrounds, and subtle colour transitions that simply are not possible on smaller canvases. The sections are smaller, and the fine brush becomes your primary tool for long stretches of each session.
If you have already finished one or two kits and want the next level of challenge without jumping all the way to a 60×80 cm canvas, this is the right move. Expect to spend 9 to 13 sessions on this size. Patience with the fine detail sections pays off significantly in the final result.
Our colour blending guide is worth reading before you start a kit at this size. At 50×60 cm, the difference between sections that are blended carefully and sections that have hard edges becomes much more visible in the finished piece.
60×80 cm: The Commitment Canvas
This is the largest canvas size we offer, and it is genuinely impressive when finished. A completed 60×80 cm painting is wall art. It looks like something you would find framed in a gallery, and that is the point. But it is also a serious time commitment, and you should go into it with realistic expectations.
At two sessions per week, this size typically takes 6 to 10 weeks to complete. That is not a discouraging number. It is simply the nature of producing a large, detailed piece of art. Many of our most satisfied customers are people who took their time with the 60×80 cm canvas, painted it across two months, and now have something hanging in their home that they made with their own hands.
One practical tip: section your canvas mentally before you start. Work one quarter at a time rather than jumping around the whole surface. This gives you a sense of completion within each session and prevents the overwhelming feeling that can hit when you look at a large canvas and do not see obvious progress. Our large canvas guide covers everything you need to know before starting a big kit.
How Experience Level Changes Everything
The estimates above assume someone who has some brush control and a basic sense of how to manage a palette, but who is not an experienced painter. Experience changes completion time in ways that might surprise you.
A true beginner picking up a brush for the first time will typically spend the first hour of their first kit just getting comfortable. How much paint to load on the brush, how much pressure to apply, when to clean between colours, how far to push a colour before it starts dragging into adjacent sections. All of that is learned by doing, and it slows you down significantly until it becomes second nature.
By your second or third kit, you are not thinking about any of that. The brush work is automatic, and you are just painting. Most people report their second kit feels 30 to 40% faster than their first, not because the kit was easier, but because they were no longer spending mental energy on the mechanics.
Custom Kits: Does a Custom Photo Take Longer?
This comes up often. People ordering a custom paint by numbers kit from their own photo sometimes wonder whether the conversion process creates more complex designs that take longer to paint.
The short answer is: not necessarily. Custom kits are available in the same canvas sizes and colour configurations as our standard kits, so the completion time range is the same. What can vary is the complexity of the source photo. A portrait of one person against a simple background will convert into a kit with large, manageable sections. A group photo in a busy setting, or a landscape with intricate detail, will produce more sections and take longer.
If completion time is a concern with a custom kit, choosing a photo with a clear subject against a simple or softly blurred background gives you the best of both worlds: a deeply personal painting, and a manageable section count. Our team reviews every custom design before it goes to production, and we can advise on whether your chosen photo will produce a particularly complex kit.
Session Length: What Actually Works
Short daily sessions of 45 to 60 minutes are the most sustainable way to work through a large canvas without losing motivation.
Most people try to paint in long sessions when they first start. They block out a Saturday afternoon and plan to make serious progress. This often works well early on, but as the kit gets closer to completion, the remaining sections tend to be the smaller, fiddlier ones that require more precision. Two hours of concentrated fine brush work causes hand fatigue and eye strain, and people start rushing to finish, which shows in the final result.
Shorter sessions are almost always better. Here is a breakdown of what different session lengths tend to produce:
30 to 45 Minutes
Ideal for busy weeks or high-detail sections. Enough time to make visible progress on one section without fatigue. Great for maintaining momentum without a large time block.
60 to 90 Minutes
The sweet spot for most people. Long enough to settle into the rhythm and cover meaningful canvas area. Short enough that concentration stays high throughout. This is the session length most experienced painters gravitate toward.
2 to 3 Hours
Fine occasionally, but hand fatigue becomes a real factor after 90 minutes for most people. Quality tends to drop in the final 30 to 45 minutes. Best used for larger, simpler sections early in the project.
Marathon Sessions
Strongly discouraged for detail work. The results are almost always visibly worse in sections painted when tired. If you want to finish quickly, two sessions of 90 minutes on the same day are better than one four-hour block.
The Practical Week-by-Week View
To make this tangible, here is how a typical 40×50 cm kit with 24 colours plays out for someone painting two to three times per week in 60 to 90 minute sessions:
| Week | Typical Progress | What You Are Doing |
|---|---|---|
| Week 1 | 20 to 30% complete | Getting comfortable with brushes, covering large background sections, and establishing your working system. The kit can feel slow. This is normal. |
| Week 2 | 45 to 60% complete | Finding your rhythm. Midground sections filling in. The image is starting to look recognizable. This is usually the most enjoyable phase. |
| Week 3 | 75 to 85% complete | Detail sections and fine work. Slower progress per session, but high satisfaction as the painting comes together. A second coat on thin colours now saves the result. |
| Week 4 | 100% complete | Final fine detail, touch-ups, and covering any remaining visible canvas. The last session often takes longer than expected, but feels the most rewarding. |
This is a realistic, sustainable pace that produces a quality result. If you are working faster, that is great. If you are working slower, that is also fine. There is no wrong pace for a hobby that exists to give you enjoyment and calm.
Tips to Paint More Efficiently (Without Rushing)
There is a meaningful difference between painting faster because you have refined your technique, and rushing because you want it done. These tips are about the former.
Work one colour at a time across the whole canvas rather than completing one section before moving to the next. Every time you load a colour on the brush, use it across every section of that colour before cleaning and switching. This dramatically cuts down on brush cleaning time, and keeps the consistency of each colour area more even.
Arrange your paint pots in numerical order before each session. Hunting for pot number 23 when you have 36 pots open eats minutes across a full session. Thirty seconds of organisation at the start saves ten minutes of frustration throughout.
Keep a small cup of water nearby for brush cleaning, and a folded paper towel for drying. Wet brushes carrying too much water dilute the acrylic paint and cause coverage problems. A quick press onto the paper towel after rinsing keeps your brush correctly loaded.
Start each session with a fresh look at where you left off. Identify which sections need a second coat from last time before painting any new areas. Catching thin coverage early is much easier than trying to go back and fill gaps once surrounding sections are done.
Our full 32 tips guide goes deeper on technique, including how to handle dried paint, the right way to approach gradients, and how to make your finished painting look professional rather than obviously paint-by-numbers.
Frequently Asked Questions
How long does paint by numbers take for a complete beginner?
Add roughly 30 to 50% to any estimate above for your first kit. The learning curve in the first two sessions is real, and you will spend time figuring out brush technique, paint consistency, and your working process. By your second kit, you will be significantly faster without trying to be. For a first kit, choose a 30×40 cm canvas with 24 colours, and budget 3 to 4 weeks at two sessions per week.
Can I do a paint by numbers in one day?
A 30×40 cm kit with 24 colours and a relatively simple design is theoretically finishable in an 8 to 10 hour day, but you would need to sustain focus and brush control across that entire time, and most people cannot. The result would also likely show fatigue in the later sections. A better approach is two full sessions across a weekend for a smaller kit, which gives the first session's paint time to dry fully before you work near those sections in the second session.
Does the subject of the painting affect how long it takes?
Yes, significantly. A design with large sky and water areas has fewer, bigger sections and paints faster than a portrait or a scene with intricate botanical detail. When browsing kits, look at the preview image carefully. If you can see a lot of fine texture, hair detail, or busy backgrounds, that kit will take longer than a simpler subject at the same canvas size.
My paint dried out. Does that add time?
Dried paint is one of the most common frustrations, and yes, dealing with it adds time to your session. A few drops of water worked into the pot with a toothpick can often revive dried acrylic paint. If it is fully dried and hard, it may not be salvageable. Our guide on fixing dried and clumpy paint covers every scenario with practical solutions.
Should I use a frame stand while painting to save time?
A frame or easel keeps your canvas at a comfortable angle, reduces neck and back strain in longer sessions, and lets you step back to assess the whole painting, which helps you spot unpainted sections more easily. If you ordered a kit with a frame option, assembling it before you start is worth the ten minutes it takes. Our frame options guide covers exactly what each choice gives you and which suits different painting styles.
Is there any way to speed up drying time between sections?
Acrylic paint dries through water evaporation, so lower humidity and slightly warmer room temperature both help. A small fan circulating air in the room speeds drying noticeably. You do not need to wait for sections to fully dry before painting adjacent ones, but painting directly into wet sections of a different colour causes mixing and muddy edges. Leaving at least 15 to 20 minutes between adjacent sections is a reasonable rule.
What happens if I do not finish my kit?
Nothing catastrophic. Cover your paint pots tightly after every session to prevent drying, and store your canvas flat or rolled in a dry space. Acrylic paint on canvas remains workable for the life of the project. Kits that sit for weeks or even months can be picked back up with no loss of quality, as long as the paints are stored properly. Life happens. The canvas will wait.
