Sadhu board nail spacing: comparing 8, 10 and 12 mm
В мені · VMENI · Updated · 2 min read
Nail spacing is the centre-to-centre distance between neighbouring nails. With the same board area and layout, 8 mm produces a denser grid than 10 mm, and 12 mm a sparser one. A larger spacing shares the load among fewer contact points, all else being equal. First-time buyers commonly compare 8 and 10 mm; wider spacing does not mean better quality.
What changes between 8, 10 and 12 mm
For a large uniform grid, point density is approximately inversely proportional to spacing squared. An 8 mm grid has roughly 1.56 times as many points as a 10 mm grid of the same type and area; a 12 mm grid has about 69% as many. The edges, cut-outs and outline change the count on a real product. These are geometry calculations, not predictions of pain or a recommended exposure time.
Choosing an initial spacing
Include 8 mm in your comparison if you want a denser grid. Many manufacturers offer 10 mm as a starting option. Do not choose 12 mm or more simply because it is labelled a progression. A smaller spacing does not become obsolete on a fixed timetable, and there is no required standing-time record for moving on.
Why two 10 mm boards can differ
Tip shape, projection, fixed or moving fastening, grid layout and the actual area contacting the foot all matter. Compare these specifications together rather than treating a spacing label as the entire design.
Spacing is not the side-to-side gap
For identical 3 mm shafts with 10 mm centre spacing, the gap between the sides is 7 mm. This is an illustrative measurement, not a recommended shaft diameter. If a description says only “distance”, look for a drawing that shows its endpoints.
What spacing cannot establish
No figure supplies individual medical clearance or a safe standing duration. More points do not remove the risk from faults, misuse or personal health limitations. Follow the actual model’s instructions; a number on a product page cannot settle health questions.
