Standards for Accessible Design (ADASAD)—refer to handrail dimensions. Current versions of these codes and standards now agree that handrail is defined as either a circular cross section with an outside diameter of minimum and maximum or a non-circular cross section with a perimeter dimension of minimum and maximum and a cross section dimension of ) maximum. In addition, the International Residential Code (IRC) includes a definition of a "Type II" handrail that allows for handrail with a perimeter dimension greater than . The IRC and residential portion of the 2009 IBC define Type II handrail as follows:

Type II. Handrails with a perimeter greater than shall provide a graspable finger recess area on both sides of the profile. The finger recess shall begin within a distance of measured vertically from the tallest portion of the profile and achieve a depth of at least within below the widest portion of the profile. This required depth shall continue for at least to a level that is not less than below the tallest portion of the profile. The minimum width of the handrail above the recess shall be to a maximum of . Edges shall have a minimum radius of .

Handrails are located at a height between . In areas where children are the principal users of a building or facility, the 2010 ADASAD recommends that a second set of handrails at a maximum height of measured to the top of the gripping surface from the ramp surface or stair nosing can assist in preventing accidents.

Clearance

(OSHA) require that the distance between the wall and handrail be a minimum of . The 1992

Accessibility Guidelines (ADAAG) stated that there was to be an absolute dimension of between a handrail and a wall. This was actually a "grab bar" dimension which was part of the 1986 ANSI A117.1. ANSI changed the notation to minimum in 1990. This was not corrected in 2010 with the approval of the new ADASAD which now calls for a minimum clearance. Codes also generally require that there be a clearance between the underside of the handrail and any obstruction—including the horizontal bracket arm. There is an allowance however for variations in the handrail size—for every of additional perimeter dimension over , may be subtracted from the clearance requirement.

Strength

Handrails are to support a continuous load of or a concentrated load of applied at the top of the handrail. As handrails come in different materials, the strengths can vary. From timber to stainless steel, it is best to pick a handrail that will be right for the area. Stainless steel will be stronger and more durable outside, whereas timber can be just as strong but less durable outside.

ADA height notations

ADA Handrail height requirements are issued to create a safe enjoyable space to enjoy for everyone. The ADA height of handrail requirements that will primarily be used by children have their own unique requirements. The top of gripping surfaces of handrails shall be 34 inches minimum and 38 inches maximum vertically above walking surfaces, stair nosing, and ramp surfaces. Handrails shall be at a consistent height above walking surfaces, stair nosing, and ramp surfaces. When children are the principal users in a building or facility (e.g., elementary schools), a second set of handrails at an appropriate height can assist them and aid in preventing accidents. A maximum height of 28 inches measured to the top of the gripping surface from the ramp surface or stair nosing. Sufficient vertical clearance between upper and lower handrails, 9 inches minimum, should be provided to help prevent entrapment.

Adult requirements

Top of gripping surfaces of handrails shall be between vertically above walking surfaces, stair nosings, and ramp surfaces. Handrails shall be at a consistent height above walking surfaces, stair nosings, and ramp surfaces.

Child recommendation

When children are the principal users in a building or facility (e.g., elementary schools), a second set of handrails at an appropriate height can assist them and aid in preventing accidents. A maximum height of measured to the top of the gripping surface from the ramp surface or stair nosing is recommended for handrails designed for children. Sufficient vertical clearance between upper and lower handrails, minimum, should be provided to help prevent entrapment. Types of handrails Handrails are available in several different varieties including wooden/timber,
