How to Use This Calculator

Enter the count of paperbacks (~0.8" spine), hardcovers (~1.2" spine), and oversized art books (~1.5" spine).
Input how many books you add per year and how many years ahead you want to plan.
Review current linear feet needed and future linear feet including planned growth.
Check the number of standard 36" shelves and 5-shelf bookcases needed now and in the future.
Verify the weight per shelf output against your bookcase's rated load capacity.

How the result changes with Paperbacks

Paperbacks	Current Linear Feet	Shelves Needed (Now)
1,000	72.9	25
3,500	239.6	80
6,500	439.6	147
9,000	606.3	203

What each input means

Paperbacks: Number of paperback books (~0.8" spine).
Hardcovers: Number of hardcover books (~1.2" spine).
Oversized / Art Books: Coffee table and art books (~1.5" spine, need deeper shelves).
Books Added per Year: How many books you add annually.
Plan Ahead (years): Plan shelving for this many years of growth.

What each result means

Current Linear Feet: Shelf length needed for current collection.
Future Linear Feet: Shelf length including planned growth.
Shelves Needed (Now): Number of 36" wide shelves for current books.
Shelves Needed (Future): Shelves including growth plan.
Bookcases (Now): Standard 5-shelf bookcases needed now.
Bookcases (Future): Bookcases with growth factored in.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Paperbacks = 100, Hardcovers = 50, Oversized / Art Books = 10, Books Added per Year = 20 = 5 input(s) provided
Calculate Current Linear Feet
Current Linear Feet = totalInchesNow / 12
12.9 = 12.9
Calculate Shelves Needed
Shelves Needed = ceil(totalInchesNow / shelfWidthIn)
5 = 5
Calculate Future Linear Feet
Future Linear Feet = (totalInchesNow + futureInches) / 12
21.3 = 21.3
Calculate Shelves Needed
Shelves Needed
8 = 8
