Most paint by numbers kits are not finished in a single evening. A standard 40 × 50 cm paint by numbers kit usually takes between 20 and 40 hours of active painting time, depending on the canvas size, detail level, and how often you paint. Some people finish smaller beginner kits over a weekend, while large detailed canvases can take several weeks.
Paint by numbers is usually more enjoyable when treated as a slow hobby instead of a project to finish quickly. It is common to paint for 30–60 minutes in the evening, then continue again a day or two later.
Average Paint by Numbers Completion Time
Here is a rough estimate based on the most common kit sizes:
| Kit Size | Average Time |
|---|---|
| Small kits (8” × 10” / 20 × 25 cm) | 2–6 hours |
| Medium kits (12” × 16” / 30 × 40 cm) | 10–24 hours |
| Standard kits (16” × 20” / 40 × 50 cm) | 20–40+ hours |
| Extra detailed/custom kits | 40–80+ hours |
These numbers vary from person to person. Someone painting carefully around tiny edges will naturally spend more time than a person filling larger sections with a wider brush.
What Makes a Paint by Numbers Take Longer?
Canvas Size
Larger canvases naturally take more time because there are more numbered sections to fill. A compact beginner canvas may have large easy-to-paint areas, while a large landscape or famous painting reproduction can contain hundreds of tiny details.
Number of Tiny Sections
The biggest difference is usually not the physical size of the canvas but the detail intensity. Kits with many small numbered spaces require slower and more careful painting.
Portraits, animal paintings, and detailed famous artworks usually take longer than simple flowers or abstract designs.
Your Experience Level
Beginners often lose the most time on small things at first — using too much paint, switching colors too often, or correcting edges repeatedly. After finishing one or two canvases, beginners usually become faster and more confident.
Experienced hobby painters also learn small tricks that speed things up, such as painting all identical numbers at once or working from top to bottom to avoid smudging.
Paint Coverage
Some lighter paint colors need two thin coats for full coverage, especially yellows, soft blues, and light pinks. This can add extra time to the process.
Better-quality acrylic paints usually provide smoother coverage and reduce the need for corrections.
How Long Does Paint by Numbers Take for Beginners?
For beginners, a standard 40 × 50 cm paint by numbers kit often takes around 20 to 40 hours to finish. That may sound like a lot at first, but few people paint continuously for hours at a time.
A typical beginner might paint:
-
30–60 minutes in the evening
-
A few hours during weekends
-
Small sections at a time
That means a single kit can easily last several weeks without feeling overwhelming.
After the first few sessions, the process itself usually becomes more relaxing and less focused on total hours.
Fastest Way to Finish a Paint by Numbers
If you want to complete a kit faster, a few small habits make a noticeable difference:
-
Start with larger color areas first
-
Paint one number across the whole canvas before switching colors
-
Use good lighting
-
Keep brushes clean
-
Close paint pots tightly so the paint stays smooth
-
Choose beginner-friendly designs with larger sections
Smaller and easier paint by numbers kits are usually the best choice if you want quicker results.
Why Some Paint by Numbers Kits Feel Slower Than Expected
Most beginners expect the actual painting to take the longest, but a surprising amount of time disappears in small repetitive tasks around the canvas.
Switching between colors too often, cleaning brushes repeatedly, reopening paint pots, or correcting tiny edges can slow the process down more than expected. Light colors also tend to need extra coats, especially on detailed canvases with very small numbered sections.
Portraits and highly detailed artworks often feel slower because they contain hundreds of tiny sections close together. Simpler landscapes and abstract designs are usually much faster to complete, even when the canvas size is similar.
Is It Better to Finish Slowly?
For a lot of hobby painters, yes.
Paint by numbers is often less about speed and more about relaxation. Rushing usually leads to mistakes, messy edges, or paint drying unevenly.
A few people like finishing a canvas quickly over a weekend, but a lot of hobby painters leave their kit on a table or desk and slowly work through small sections over several weeks.
That slower rhythm is one reason paint by numbers became popular as a quiet screen-free hobby after work.
Do Custom Paint by Numbers Take Longer?
Custom paint by numbers kits often take longer than regular designs because they usually contain more detail and color transitions.
Pet portraits, wedding photos, and family pictures typically include:
-
Smaller numbered sections
-
More subtle shading
-
Facial details
-
Complex backgrounds
A custom paint by numbers canvas can sometimes take 40 hours or more depending on the image quality and canvas size.
Final Thoughts
Most standard 40 × 50 cm paint by numbers kits take around 20 to 40 hours to complete, although detailed custom canvases can take much longer.
The actual pace depends less on skill and more on how detailed the image is and how you prefer to paint. Large famous paintings, portraits, and animal designs usually take the longest because of the amount of tiny sections and shading.
For beginners, smaller and simpler canvases are often the most enjoyable starting point because progress feels visible much faster.
If you are new to the hobby, starting with an easy paint by numbers kit usually makes the experience more enjoyable and less frustrating.
