Length basics

Length is measured from tip to finger rest. The right size balances control and efficiency.

Service	Recommended length	Notes
Precision bobs, short layers	5.0”–5.5”	Maximum control for detail work
Everyday salon cutting	5.5”–6.0”	Versatile for blunt and point cutting
Dry cutting, slide cutting	6.0”–6.25”	Longer blade rides hair sections smoothly
Barbering, scissor-over-comb	6.5”–7.0”	Covers more hair per stroke
Carving/texturizing	5.75”–6.25”	Pair with convex edge for fluidity

Decision checklist

Service mix: Track the percentage of services requiring precision vs speed.
Hand size: Larger hands often find balance with slightly longer blades; verify using Tool Fit Assessment.
Edge type: Convex edges in longer lengths excel at slide work; micro-serrated shorter blades grip blunt lines.
Client texture: Thick/coarse hair benefits from longer blades; fine hair may demand shorter lengths for control.

Practice scissor-over-comb with 6.5”+ shears for two full mannequin cuts before using on clients.
For detail work, rehearse fringe and perimeter refinement with 5.0” shears to ensure you can maintain tension.
Time each service and note any fatigue; adjust length if your hand feels overstretched or cramped.

Carry two lengths in your service kit:

Primary length that covers 80% of appointments.
Secondary length for specialty work (e.g., 5.25” detailer + 6.5” scissor-over-comb).

This rotation extends edge life and keeps your hand posture healthy through varied motions.

Balance point: Some brands shift weight toward the tip on longer blades; test before buying.
Handle pairing: Long blades often come with crane or offset handles to stabilize leverage.
Blade geometry: Sword or bamboo blades add rigidity for longer lengths—study options in Blade Types.
