Engineer hardwood pile length calculation problem

So my living room is 250sqft (20'5" x 12'8"), I got 12 boxes of hardwood piles (Jatoba) in total. The piles came in different length and count, longest is 6' in 6 pieces, 4' in ~ 10pcs, 3' in ~ 10 pcs, 2.5' ~12 pcs, 2' are in the most ~ 50-60 pcs, 1.5' ~ 10 pcs. I need some help with the math to figure out how to install these piles to have with nice alignment, with minimal waste and industry code compliant. Thanks!

What did the boxes say the square footage of each was? Good indicator. Please fill out your profile so we know where you are located. Our advice can be better geared for you that way.

I also suspect that he member is not domestic as he refers to cases of flooring as "Piles".

Save the larger length pieces for the center of the floor where you wil actually see the wood planks. Consolidate as best you can the smaller pieces to be located underneath furniture and in less visible areas. Utilize the end cuts from one row as the starter piece for the next row to minimize waste.

Thanks for the reply everyone! More details about my project, location is San Jose in Norcal, my subfloor is plywood in 9sqft squarish shapes jointed with nails, currently we've used self leveling to make it flat.Each box I ordered covers ~ 24 sqft with most (about 2/3 of the flooring panels coming in size of 2 ft in length,4.5ft in width. Rest panels are of the same width but various length of 6ft (the least in quantity),4ft (the least in quantity),3ft,2.5ft and 1.5ft.

I have two basic questions. First is about flooring direction. Based on the structure of my living room (the red cross area is for flooring). I'm planning to align the flooring in parallel to my patio sliding door. So when I enter the living room from kitchen or main door, the flooring is perpendicular. Some online posts say that it's advised to arrange the flooring across the subfloor joints, but my subfloor plywood are in squarish shape with joints all around, it doesn't seem to apply to my case. Question is does the direction of my planned flooring installation looks right?

Second question is about how to get the random length panels staggered to avoid running into 'H' joints and ensure the minimal 8" gap between the end joints of panels in adjacent rows. Measurement of the living room is 20'5" X 15'8".Since 2/3 of the boards are in 2ft length, I'm thinking about starting the first 4 rows with 6ft, 4ft,3ft and 1.5ft panels respectively (like in the picture) and using mostly 2ft panels for the rest of the row. Then repeat the 4 row alignment in a set for the rest 26 rows. Does this make sense or I'm totally wrong?

It is a random pattern, you hand lay (rack) out several rows to determine your pattern and then nail then one at a time. There is no way we can advise as we are not on site. Weave the large boards into the mix as you go, but resist the temptation to use them all up quickly. Avoid simple staggers as you have done as it results in an "H" pattern which takes away from the random nature of the boards.
