18 Year 10 Month Break
Using the method employed by Andrew Hussie in an old Formspring post, given that MSPA started full production on 09 Mar 2008, then to produce the 9633 pages since at the perfectly fine rate of one page per day would take until 25 Jul 2034, earning him a 18 year 10 month break starting from today.
Here's a graph if you want to see how it has changed over time.
Ninja
So I looked around for prior art before I started coding this up, but shortly thereafter notEgbert
published an absolutely marvellous and comprehensive "Measuring Homestuck" report that meets and surpasses many of the plans that I had. You should definitely check out this statistically significant result!
how big is it like the size of texas
Homestuck is about 274% the size of the Lord of the Rings, 170% the size of the King James Bible, 122% the size of the Harry Potter series, or 75% the size of A Song Of Ice And Fire (the five books so far)
…OK, that needs some context and justification. notEgbert
has constructed and refined a measure that attempts to squash the multimedian aspects of the works of Hussie down into an adjusted word count so that story size can be compared against that of other plain text works. Briefly, we count (9 + 0.6 * size/KB) words for each image, and (20 + 0.1 * size/KB) words for each swf. Combining this with my figures and existing word count, the adjusted count for Homestuck is currently 1318688 words.
For more detail and discussion of the comparison method, please see the "Measuring Homestuck" thread, where notEgbert
explains:
…the parameters and methods used for wordcount equivalence are very subjective and estimated, but are all intended to be conservative estimates and measures, based at least inpart on common standards, where available.
FAQ
 How did you derive these numbers?
 From code running over my offline archive
 What's a panel?
 An image, a Flash, a section of text, or a pesterlog, including images that are linked out to from the regular numbered pages.
 What's a "day"?
 Time has zones. I have found that to overlap best with a typical Hussie waking/working day, it works best to have a twentyfour hour day begin and end at 10:00 a.m. in the Boston time zone. And that for days of Homestuck to tie up best with those called out in the story, the first day is known as day zero rather than one.
 What does "about N% of" mean? It looks wrong, because...
 There are a bunch of different ways to measure the size of this multimedia thing. The reported proportions average the three stats reported here  pages, panels and words. (I used to also include days, but Gigapausing the update stream broke that.)
 Which words do you count?
 I consider the actual text, and also text I have transcribed from image etc. panels. I apply a bunch of little rules in code to decide exactly what is a word, but none of them alter the count very much. Here are more details and an illustrative example.
 How long is a piece of [S]
tring?
 I count the start of a Flash as when it has loaded, and the end as when both the visual and audio content have ended; in turn this means they have ceased, or they have almost completely slowly faded, or they have started repeating. YMMV. I didn't time walkarounds or other Flashes that are interactive enough that there is no set linear path through them; merely having to (read and) click through is OK though. I appreciate that our subjective boundaries may differ: maybe you wouldn't count [S][A6I3] MINISTRIFE!!! the same, or at all.
 If I add up pages in A1, A2, A3, I1 and A4, why is it less than the pages in Part 1? (etc.)
 I don't count every page as being part of an Act. The pages that come between the End of Act N page after the curtains close and the Act N+1 page where they open again — not part of either Act. You could insert prologues and epilogues, but to me it seems unnecessary arbitrary editorializing so I just go with
WordCurtains Of God. The pages are still counted in the next layer up.
 I did some other arithmetic, and shouldn't there be (x  1901) pages in Homestuck?
 There are some missing/extra page (and image) numbers.
 HSA6A5A1 is the same number of days as HSA6A5?
 Well, the act structure is weird! A6A5A1 wraps around the sides of A6A5A2. Subtracting the days of the inner act seemed just as arbitrary a choice to make.
 Also, you should count two pages rather than one during the x2 part of that act!
 That's good, because I do! The pages are represented separately by the data that drives MSPA, so my existing stats machinery automatically counted them up that way.
 No, you should count each pair as a single page!
 Well, I can't please both of you.
 Why don't JB or RQ show days?
 I'm using the timestamps on the text files that drive the official site to reporting how many days pages were published across. RQ doesn't have any timestamps. JB has some that are misleading because it was bulk imported from a web forum that preceded the MSPA site.
 Where are the PS extras? Where is SB&HJ?
 They are missing at least for now, apart from SB&HJ panels directly linked from HS.
