Stem and leaf plot maker
Paste your numbers and get an ordered stem-and-leaf plot with its key — plus the median, quartiles and mean to check your working.
Paste raw numbers — separated by spaces, commas, tabs or new lines. Don’t count them first; the tool does that.

How to make a stem and leaf plot
- Paste the numbers (any order).
- Stems and leaves are chosen automatically; set a leaf unit (e.g. 10 or 0.1) to override.
- Copy the key under the plot so readers know what “7 | 2” means.
- Download PNG or SVG.
How a stem-and-leaf plot works
Each number is split into a stem (all but the last digit) and a leaf (the last digit). For 72, the stem is 7 and the leaf is 2. Leaves are written in order beside their stem, so the plot is both a sorted list and a sideways histogram. The key, such as “7 | 2 = 72”, tells readers the place value.
With a leaf unit of 10, 342 becomes stem 3, leaf 4 (340, rounded). With 0.1, 5.7 becomes stem 5, leaf 7. Stems with no leaves are still listed so gaps stay visible.
Questions
How do I find the median from a stem-and-leaf plot?
Count the leaves: the median is the middle leaf (or the average of the two middle leaves). The summary table shows it so you can check.
Can a stem-and-leaf plot have decimals?
Yes. Set the leaf unit to 0.1 so 5.7 is shown as 5 | 7.
