Can I use white paper instead of a grey card for white balance?

Is a plain white sheet of paper acceptable for setting white balance, or does a calibrated grey card make a meaningful difference? I’ve tried paper and it seems to work fairly well, but I’m wondering how accurate it is and what limitations to watch for.

A purist would say it's not good enough because you can't guarantee the consistency of the white in the paper. However in my personal experience it's plenty good enough. I've used sheets of paper, bleached coffee filters, tops of Pringles cans (when they had a frosted top) and everything was fine. I've also used more expensive tools like the CBL Lens.
However, a word of caution: if your goal is color accuracy then it's not good enough. You need proper tools. If your goal is to get very close then it's perfectly fine to use paper. Remember that in many cases a white balance choice is an artistic choice more than anything else. And there are many reasons to choose something other than what is technically correct.

Yes—plain white paper can be good enough for a quick custom white balance, especially if you just want to get close. Many photographers successfully use paper and other neutral white objects for this.
The difference is consistency and accuracy. A proper grey card is made to be neutral and repeatable, so it’s the better choice if color accuracy matters. Paper can vary in whiteness, may contain optical brighteners, and can introduce errors. It can also show texture, watermarks, or show-through from printing or writing on the other side, especially in strong light.
If you use paper, use a clean, plain, unprinted sheet—ideally several sheets stacked together to avoid show-through. Check for watermarks and visible texture.
So: for casual use or a close approximation, white paper is usually fine. For reliable, color-accurate results, use a proper grey card or dedicated white-balance target.
