There really isn't any set length. The only thing I find with my own writing is that the chapters tend to get shorter as the pace increases.I am writing my first mystery novel. My question is : How long should a chapter be? I would love to hear everyone's opinion? Thanks!!!
Chapters are whatever length they want and need to be.

The first three to four chapters are usually long but the rest of the book should be a lot shorter.

I don't believe this is true. Is this just something you've observed in your own writing or reading?
Absolutely. Each chapter should tell its own mini-story. When that story's done, so's your chapter.
