Instantly convert paper weight into sheet count, work out cutting yield (ups), and compare GSM options for any sheet size — built for offset & packaging buyers.
This tools section is actively evolving — always confirm figures with our team before production.
Line up different sizes, GSMs, or paper types side by side. Cost columns use the single Price set on the left for every row — only meaningful when comparing specs from the same supplier quote.
Set a size/GSM on the left, then click "Add Current Spec" to start comparing — add up to 6.
Convert either direction — same paper spec, same pricing.
