The Barkley Presidential Length Index
The Barkley Presidential Length Index (BPLI) uses a formula of height multiplied by length of term to measure the inch-hours served by each chief executive.
William Henry Harrison, at a respectable 5’10” but only 33 days in office, has the lowest BPLI. Abraham Lincoln (6’4″), had he lived, would have had the highest BPLI of any two-term president.
The all-time highest BPLI belongs to four-term president Franklin Roosevelt, if measured standing rather than in his wheelchair. However, had Lyndon Johnson (6’3″) run again for reelection in 1968 and completed 9+ years in office, he would have become the new BPLI leader.
