I suggest you go with Igloo font. As long as you don't require italics, or have need to describe something that's warm, it's the perfect all purpose font. I'm finding that my chapters sort of follow a rhythmic pattern, short-medium-short-long. Thus far though, I only have four chapters so I might be overstating things.
I think so long as your chapter serves its purpose, and is well written, the lengths sort of meld together. I couldn't tell you what the longest chapter of The Martian is, but I know none of the seemed too long to me. The chapters all had a clear driving problem to be solved, and I'm sure their lengths had variation, but I wasn't focused on counting words. I was focused on 'Oh my God, his potatoes exploded!' I think the shortest chapter is when the Chinese officials decide to help NASA. Its literally one scene, I think less than 1k words. But it didn't seem too short. China helps America; the exploration of space is bigger than one nation. Got it. If your chapter length is distracting your readers, they might not be engaged by your story, or maybe your critiquers are being a little too picky. I never comment on chapter length. This thread makes me realize something. Chapter length is not really something I've ever considered in other people's writing; only MY OWN.
My chapter length tends to be unpredictable. I finish chapters whenever the depicted situation has lost intrigue, the majority of my drastic location transitions occur between chapters for continuity sake but occasionally describing the travel to said location makes for much needed down time after a narrative revelation.
Question: when you speak of chapters, are you thinking of scenes instead? The length of my chapters varies a lot, but within a chapter I can have two to thirty scenes (separated by spaces/symbols/etc), so that's what counts, right? I try to have scenes not longer than 6000 words, and that's already a bit too much.
One famous writer said chapters should be the correct length for the chapter. Tell what needs to be told but dont pad it out with filler. Some of that may depend on the style. Old English authors were paid by the word so they had incentives to add long winded descriptions of the flowers in the garden where the murder happened. Personally I would prefer a chapter to be one scene, or a few closely related ones.
Have you tried planning first? What is the chapter supposed to do ? What is the change in the arcs for plot and character? What is the action/reaction. Who does what why where when and how? And how does this relate to other events. Do you develop the character any, inform some bytes of the backstory, or otherwise use that chapter?
Sounds more like what I do at times with shorter pieces that I write. Put in everything that seems like a good idea and then cut out what is not really needed.
The best books are the ones where I do not realise that I am turning pages as fast as I can while seeing a movie in my mind. That is a problem with using a kindle. It has a slight interruption at each page change. OTOH most novels are not written that well. They take some effort and the movie is not as sharp or as fast as the few really well written ones I have read. So for them kindle is not a drawback.
In my WIP chapters range from 200 to 2000. The average chapter is about 1000 words. I think I have too many chapters, and may well combine multiple together after I finish writing. I use chapter titles to focus my writing, as a pantser it works well.
For me the average chapter varies between 1 250 words and 4 000 words. Uncommonly more or less because chapters too short feel rushed to me and chapters too long are too slow (and I am unable when reading to put the book down without finishing the chapter, so yeah...) In my WIPs it's much lower, a lot have to be added as I later think of things that should be part of it, things I don't feel like/know how to explain(ing) and filling up gaps I deliberately leave so to explain when I fleshed the world a bit more out.
