Jigsaw Puzzle Time Estimator & Log
Estimate how long a puzzle will take based on piece count, your experience, and difficulty, then log finished puzzles and track your best pace.
Your puzzle log
About this jigsaw puzzle estimator
Enter a puzzle's piece count, pick your general experience level (beginner, average, or expert), and its difficulty (easy, medium, or hard), and the estimator gives a time range for finishing it — a central estimate plus a rough low-to-high window, since actual pace varies even for the same person on the same size puzzle. The estimate is built from an assumed pieces-per-hour rate that adjusts with both your experience level and the difficulty multiplier you select.
Once you've actually finished a puzzle, log it with its name, piece count, and hours spent, and it's added to a running personal log. Career stats track your total puzzles completed, total pieces placed across all of them, and your best-ever pace in pieces per hour, with your fastest puzzle specifically flagged as a personal best in the list below, sorted with your most recently finished puzzles at the top.
Piece rate is a rough guide, not a race — image type matters more than piece count for how long a puzzle actually takes. A busy landscape with lots of similar-looking sky or foliage can easily take twice as long as a photo with clear shapes and distinct color blocks, even at the exact same piece count, since sorting pieces apart is genuinely harder when everything looks alike.
Your puzzle log is saved automatically on this device; nothing is uploaded anywhere, so your career stats keep building the more puzzles you add.
Frequently asked questions
Why is the estimate a range instead of one number?
Actual pace varies even for the same person working the same size puzzle, depending on focus, breaks, and the image itself. The range reflects that realistic variation rather than promising false precision.
Does image type really matter more than piece count?
Often, yes. A busy landscape with lots of similar sky or foliage can take twice as long as a photo with clear shapes and distinct color blocks, even at the same piece count, since sorting pieces is harder when everything looks alike.
How is my personal best calculated?
By pieces per hour across every puzzle you've logged — whichever finished puzzle has the highest rate gets flagged as your personal best, regardless of its total size.
Can I log a puzzle without estimating it first?
Yes, the estimator and the log are independent. Log any finished puzzle's piece count and hours directly, whether or not you used the estimate beforehand.
Is my puzzle log saved or uploaded anywhere?
It's saved locally on this device automatically. Nothing is uploaded anywhere.
