The honest answer: it depends on canvas size, drill type, and how many colors the design uses. Here's a realistic breakdown by project type, so you can pick a kit that matches the time you actually have.

Time estimates by canvas size and drill type
These are realistic ranges for a moderately detailed design, based on typical working pace. Highly detailed designs with many small color-change points will run longer than these estimates.
| Canvas Size | Full Drill (Round) | Full Drill (Square) | Partial Drill |
|---|---|---|---|
| 30x40cm | 10–18 hours | 13–22 hours | 5–9 hours |
| 40x50cm | 18–28 hours | 22–34 hours | 9–15 hours |
| 50x60cm | 28–42 hours | 34–50 hours | 15–24 hours |
| 60x80cm | 42–65 hours | 50–75 hours | 24–38 hours |
Four factors that change your actual time
Two people working the same canvas size can finish hours apart. Here's what actually moves the number.
Number of colors
A design with 10 colors is faster to work through than one with 50, since fewer colors means less time spent switching diamonds and re-sorting.
Round vs. square drills
Square drills need more careful alignment since they sit flush with no gaps. Round drills are faster to place but leave small visible gaps between diamonds.
Design density
A design with lots of small detail and frequent color changes takes longer than a simpler design with large blocks of a single color, even at the same canvas size.
Working method
Sorting all diamonds into a tray before starting and working one color at a time across the whole canvas is noticeably faster than working section by section from a loose pile.
Full drill vs. partial drill, side by side
More coverage means more time, every time
Full drill kits cover the entire canvas in diamonds, which is why they consistently take longer than partial drill kits that leave background sections blank or pre-painted. The finished look is different too: full drill has a denser, more textured sparkle across the whole piece, while partial drill lets the printed background show through for a more painterly contrast.
If your priority is finishing a piece quickly, a smaller partial drill canvas will get you there fastest. If you want maximum sparkle and don't mind the extra hours, full drill is worth the time.

Quick questions
How long does an average diamond painting take to finish?
A standard 30x40cm full drill canvas with a moderate color count typically takes 10 to 20 hours total, spread across several sessions. Size, drill type, and color count all shift this range.
Does full drill take longer than partial drill?
Yes. Full drill kits cover the entire canvas in diamonds, so they take noticeably longer than partial drill kits, which leave some background areas blank or pre-painted.
Do square drills take longer than round drills?
Generally yes, by a small margin. Square drills require more careful, deliberate placement since they sit flush against each other, while round drills are more forgiving and place slightly faster.
Can I finish a diamond painting in one sitting?
Only very small canvases with few colors are realistic to finish in one sitting. Most diamond paintings are designed to be worked on across multiple sessions over days or weeks.
What's the fastest way to speed up a diamond painting project?
Sorting diamonds into a tray by color before starting, working one color at a time across the whole canvas, and choosing a design with fewer total colors are the most effective ways to cut down total time. Our Diamond Painting Tips guide covers more habits that speed up the process.
