Chair Seat Height for Elderly Parents: 17 to 19 Inches
Seventeen to nineteen inches is the band that makes standing up possible and transfers level. Here is how to measure it on the person, not the furniture.

Bed Height for Elderly Parents: Feet Flat on the Floor
The right bed height puts their feet flat on the floor with knees near a right angle, usually 20 to 23 inches to the top of the mattress. Here is how to fix a bed that is wrong.
Doorway Width for a Walker: Why the Door Size Is Not the Opening
A 32-inch door leaves about 30 inches of clear opening, which suits most walkers. A 28-inch door leaves about 26, which does not. Measure the gap, not the slab.
Hallway Width for a Wheelchair: 36 Inches to Pass, 60 to Turn
Thirty-six inches is enough to travel straight down a hall. Turning around needs sixty. Turning into a doorway needs more than either, which is the part that catches people.
Portable Ramp Weight Capacity: Add Up the Chair, Not Just the Person
Most portable ramps are rated 600 to 800 pounds. A power chair alone can be 320. Here is how to do the arithmetic, and what voids the rating.
Ramp Handrail Height: 34 to 38 Inches, Both Sides
Handrails go 34 to 38 inches above the ramp surface, on both sides, and must run 12 inches past each end. Required on any ramp rising more than 6 inches.
Wheelchair Ramp Landing Size: 60 Inches, and Where You Need One
A landing must be 60 inches long, at least as wide as the ramp, and 60 by 60 at every turn. You also need one every 30 inches of rise.
How Long a Ramp for 2 or 3 Steps? Longer Than You Think
Two steps need about 14 feet of ramp. Three steps need about 21 feet. Here is the arithmetic, and what to do when that will not fit in the yard.
Grab Bar Mounting Angle: Horizontal, Vertical or Diagonal
Horizontal for pulling across, vertical for standing up and stepping in, diagonal for neither reliably. Which one to use where, and why diagonal is so common.
Grab Bar Distance From Wall: Why 1½ Inches, Exactly
The gap between a grab bar and the wall should be 1.5 inches. Too little and your hand will not fit. Too much and your forearm can slip through in a fall.
