20mm nail spacing means the tips of adjacent nails on the sadhu board are 20 millimeters (2 centimeters) apart. This is an advanced-level spacing: fewer nails per square centimeter, so each nail carries more of your body weight, producing sharper, more focused pressure. 20mm is typically the level daily practitioners reach after months or years of practice — it demands calm breathing and steady balance. METADESK founder Eugene Oliynyk has practiced daily on 20mm since 2018. Beginners should not start here — begin at 8-10mm and build up over weeks and months.

Frequently asked questions
Is 20mm dangerous?
Not for prepared practitioners. Weight still spreads across hundreds of tips.
How long to reach 20mm?
Typically 6-12 months of consistent practice, starting from tighter spacings.
Does it hurt more than 10mm?
Yes, meaningfully. Each contact point carries more pressure.
Can I get custom 20mm?
Yes. METADESK builds 20mm boards on request.
