How it works / formula

Approx text lb ≈ GSM × 0.270.
Approx cover lb ≈ GSM × 0.370.
Approx bond lb ≈ GSM × 0.266.
Factors are industry rules of thumb.

Worked example

Frequently asked questions

Why don’t converters always match?

US “lb” depends on basis sheet size. Always confirm with your paper brand.

Is lb text the same as lb cover?

No. Basis size differs — always note text vs cover when you convert.

Will this match every mill?

It is an approximation for planning. Supplier charts win for purchasing.

Does GSM change print DPI needs?

Not directly. Stock still affects feel, show-through and ink load.
