Knots per square inch is the number everyone quotes — and the one most people misread. 🧶
Here's the secret: higher isn't automatically better. KPSI isn't a grade for quality, it's a roadmap to the style you actually want.
• Under 80 — village and tribal rugs like Gabbeh, Baluch and Qashqai. Coarser weave, bold geometry, rustic character.
• 80–200 — solid everyday luxury. Hamadan, Heriz, Tabriz. Durable, beautifully detailed, built to last generations.
• 200–400 — very fine work. Kashan, Isfahan, Nain and fine Tabriz, where curvilinear designs get ultra-crisp.
• 400–1,200+ — the pinnacle. Top-grade Nain, Isfahan silk-foundation pieces, the finest silk rugs. Rare and investment-grade.
Design, artistry, wool quality and age matter just as much.
