What your chart size says about how you listen
Twenty positions is by far the most chosen format, and the reason is not laziness
When you build a chart on ChartFM, you choose how many positions it will have. There is no mandatory default, the range is wide, and yet the choices cluster around a handful of numbers.
The most common size, by a comfortable margin, is twenty positions. Second comes ten. Then, well behind, a hundred, fifty and thirty.
Round numbers dominating is no surprise. What is interesting is which round number won.
Why twenty and not ten
Ten is the classic music chart number. Everyone grew up on top tens. And yet twenty is almost twice as popular on ChartFM.
The likeliest explanation is about what hurts to cut. A normal week of listening produces more than ten songs worth mentioning. With ten positions, you spend more time deciding what to sacrifice than ordering what you like.
Twenty fits almost the whole week. You still order the top carefully, but you do not have to discard anything that mattered.
What each size does to your chart
The three bands behave very differently over time.
- Ten positions. High turnover. Almost every week has a new entry, and each debut is an event. Good if you like watching movement.
- Twenty positions. Stable top, dynamic middle. The first five repeat for weeks, and the fight happens between sixth and twentieth.
- Fifty or a hundred. Static base and a long tail. The last positions tend to be a song that entered once and stayed. Good as an archive, poor for watching movement.
None is better. But if you complain that your chart never changes, the size may be the cause before your taste is.
A bigger chart carries no more weight in the ranking
One common expectation is worth undoing: publishing a hundred positions instead of ten does not increase your influence on the Global 100.
The points scale drops fast. The positions you gained by expanding the chart are worth little, and the ones that decide the ranking are the first few, which you would have had anyway.
So choose the size for what it does to your experience, not as strategy. Strategically, it makes no difference.
A case of its own: a hundred positions
A hundred shows up more than fifty, which is curious. Fifty would be the natural middle between twenty and a hundred.
The most plausible reading is that a hundred is not a size choice, it is a purpose choice. Someone building a hundred positions is usually not making a ranking, they are making a record of what they listened to. That is a different use of the tool, and there is nothing wrong with it.
Thirty positions follows just behind and probably serves people who found twenty tight without wanting the commitment of fifty. It is the size for someone hearing a lot of new music each week.
How to choose yours
If you are starting out, the useful question is not how many songs you heard, it is how many you can order with conviction.
Ordering means comparing. Comparing twenty songs in pairs is already work, comparing a hundred is impossible to do honestly, and the result is that the bottom half sits in an invented order. A well ordered chart of ten says more about you than one of a hundred where only the first fifteen were thought through.
The practical advice is to start small and grow when cutting starts to hurt. Growing is easy and does not touch your history. Shrinking is the hard part, because it means deciding what leaves.
Frequently asked questions
- Can I change the size later?
- You can, and starting at ten then growing is common. The history of previous weeks does not change.
- Do I have to fill every position?
- No. A chart with fewer songs than the size you chose works normally.
- Does the size show to people reading my chart?
- The track count shows, alongside the interactions. It is context, not judgement.
