How many novel pages is one handwritten page?

“Novel pages” is pretty vague.

You might want to gauge your writing according to typed text – say, a handwritten page like you described is probably about two pages typed in Word, double-spaced using 12-point Times New Roman. (That’s just my guess.)

You might use word count. A novel is in the range of 16,000 words (young adult) to 40,000 or 80,000 words or more for adult fare (and Harry Potter). Words on a page depends on how the publisher prints the book. Your handwritten words per page count will depend on your handwriting, the paper size and how it’s ruled.

I glean from your desire to compare your output to a novel that you are writing something for others to read. You should be using a computer. Seriously, handwriting is only for sketches of projects and recording of random ideas. Writing is rewriting. Even for first drafts it’s ridiculously optimistic to think that the first time through you’ll have anything worthwhile. Learn to use a computer. It’s worth the effort.

If you assume 150 words per page for handwritten pages and 500 words per page for typewritten, then one handwritten page front and back = 3/5ths of a typewritten page.

Pages is a meaningless measure. A novel is typically around 90,000 to 120,000 words (but could be much more or much less). The size of the print and the dimensions of the book page determine how many pages.

I know people whose handwriting is the equivalent of 8-pt. type and others who write in 24 pt. There is no way we can make an estimate for you. We don’t know what you think is “medium.”

Count how many words are on one of your own typical handwritten pages. Then multiply that by the number of pages you have. That will give you an approximate word count.

If you’re looking for an estimate in manuscript pages rather than finished, printed book pages, remember that standard manuscript format is double-spaced (that is, has a line of space between every two lines of text), so there would normally be about 250 words on a “typed” manuscript page in a standard 12-point font, double-spaced.

There is nothing wrong with writing a draft by hand. I often start in a notebook; Nabokov wrote his novels on index cards. You’ll need a word-processed electronic manuscript when it comes to serious submissions to a publisher, though, and that means a lot of transcribing.

I found a set of stats for the Harry Potter novels online in several places but didn’t find an authoritative source. They’re probably close enough to serve as an illustration. Here’s one:

Philosopher’s Stone- 76,944 words
Chamber of Secrets – 85,141 words
Prisoner of Azkaban – 107,253 words
Goblet of Fire – 190,637 words
Order of the Phoenix – 257,045 words
Half-Blood Prince – 168,923 words
Deathly Hallows – 204,796 words

I’d say the number of hand written words is not an accurate assessment since some people write in big letters and other write is small letters. As suggested, word count is probably more to the point. Check out @Jeruba‘s answer.
