As I often say in most cases, try to find your own style and sweet spot. Write a bit, like 5 or 10 chapters before starting to publish and you will realize what is your usual word threshold for each one and either stick with that and choose release schedule according to how much time you have to spend on writing one chapter (including some time for a breather, like break days) or try getting more or fewer words to the match the desired amount.
Also, it can depend on the type of story a lot. For example, action-adventure will be easier to write short chapters and release often, thanks to something engaging happening all the time or most of it, while slower genres like Slice of Life, usually go with longer chapters due to how emotions, dialogue and events are described, to not finish a whole chapter with the feeling like it's empty of anything meaningful.
In my own example, I choose 1-2 releases per week from the very beginning, after I wrote 3 chapters, each taking me 1-2 days, depending on the level of detail I wanted to put into them. I started with 2.5k words in the first one, but now, after almost 3 months of constant writing, I constantly hit double that number. You naturally get better and less awkward the more you write and it's clearly noticeable for you and your readers both. Don't get discouraged at the start. I was taking much more time and making many more mistakes in the first chapters and now the flow of my writing time got slightly less chaotic.
So in other words, write, write, write, write and then choose the style that suits you and your story the best. Quantity doesn't have to mean the lack of quality. Try to not burn yourself out while getting constant messages from readers to post more of the story. It's natural that people will want more of the thing they enjoy. Respect your time and health.
