| Bars run | Up from baseline | Right from baseline |
| Best for | Time-series, short labels | Ranked categorical, long labels |
| Typical x-axis | Categories or time | Values |
| Label rotation issues | Common past 6–8 categories | Rare |
| Reads naturally as | Trend over time | Ranking from top to bottom |
The terminology debate
In Microsoft Excel, "bar" specifically means horizontal and "column" means vertical. In most other software (Google Sheets, Tableau, Apple Numbers, every D3 example you've ever seen), "bar chart" is the umbrella term for both, and you switch between vertical and horizontal with an orientation toggle. We use the latter convention on this site.
Use vertical (column) when…
Categories have a natural left-to-right order — usually time. Months, quarters, years, days of the week. Also when category labels are short (single words, short phrases) and there are fewer than about eight categories. Vertical bars feel intuitive for "how did this number change over time?"
Use horizontal (bar) when…
The data is ranked, not ordered. Long labels (multi-word category names). Many categories (more than eight). Survey results, leaderboards, top-N lists. Horizontal bars give the labels room to breathe and let the reader scan top-to-bottom following the rank.

Sometimes either works. Six categories, medium-length labels, no time dimension — pick whichever fits the available space in your layout. Vertical works in a wide, short slot; horizontal in a tall, narrow one. Don't agonize.
A small etiquette point
If you're writing for a finance audience that uses Excel daily, expect them to call vertical "column" and horizontal "bar". If you're writing for a general audience or a design-leaning team, "bar chart" works for both and the orientation is just an attribute. Pick the convention that matches your reader.
