Quick answer: most people finish a standard 40cm x 50cm (16x20") paint by numbers in roughly 15–25 hours of brush time. Painted in relaxed 30–60 minute sessions, that's typically two weeks to two months on the easel — and that slow pace is a feature, not a flaw.
It's one of the most-asked questions in this hobby, so here's an honest breakdown — including what makes a canvas faster or slower, and why "how long" is really a question about how you like to unwind.
The honest math
| How you paint | Sessions | Calendar time |
|---|---|---|
| A short session most evenings (30–45 min) | 20–35 | 3–6 weeks |
| A few longer sits per week (1–2 hrs) | 10–15 | 2–4 weeks |
| Weekend marathoner (3+ hrs at a stretch) | 5–8 | 1–2 weekends… plus recovery for your neck |
Ranges assume the standard 40cm x 50cm canvas most of our kits use. Everyone paints at their own pace — these are typical, not targets.
What makes a canvas faster or slower
- Section size. Designs with big, generous shapes — open skies, broad petals like Blossoming Hues — fill fast. Densely patterned designs take longer per square inch.
- Detail density. Our Klimt-inspired kits are dotted with hundreds of small golden orbs — gorgeous, absorbing, and deliberately slower. Painters pick them for the long meditative haul.
- Custom photos. The Create Your Own kit converts your photo into sections — faces and fur carry fine detail, so budget toward the higher end and treat the slowness as time spent with the memory.
- Your inner perfectionist. Crisp edges and second coats add hours — and are usually worth it (see our tips guide).
Why slower is actually the point
Nobody buys a puzzle to finish it fast. The 20-ish hours a canvas asks of you is exactly what most of us are missing: recurring, screen-free, single-focus time. Painters consistently describe the middle sessions — pot open, brush loaded, hunting number 14 across the canvas — as the most relaxing part of their week. If you want that effect on purpose, our piece on painting as a wind-down ritual goes deeper.
Can you speed it up?
A little, without hurting the result:
- Paint one color at a time across the whole canvas — less rinsing, less friction.
- Do big sections with the large brush early; save details for fresh-eyed sessions.
- Keep a dedicated spot set up so starting a session takes ten seconds, not ten minutes.
- Recruit help. A shared canvas genuinely halves the hours — that's the premise of our painting-together picks.
Planning around a date?
If the finished painting is meant as a gift, work backwards: allow around 3-5 days of order processing plus around 5 to 15 business days for delivery, then your painting hours, then a few days of drying before framing (the 16x20 wooden frame fits the standard canvas). For a birthday two months out, ordering this week is comfortable; two weeks out is a sprint — doable, but choose a design with generous sections.
