resistor tolerance query

In front of me, a schematic calling for 10% tolerance resistors.
Digikey seems to be big on 5%. Would subbing 5% for 10% be a disaster?
I'm building a tuning standard. Thanks for any advice offered.

Of course not, it would be more than ideal. Tolerance means that a 100k resistor rated at 20% could actually measure between 80-120k.

If a schem calls for 10% tolerance resistors, they're basically saying "these here resistors don't really need to be that close"
So a schem calling for 10% should easily be happy with anything less than 10% tolerance.  It'll just mean that the resistor's actualy value should be closer to 100k, which you don't necessary need, but won't hurt.
