Hi.
The standard is to add .125” on each side. If you are unsure you can go to .25.” For very large format, like tradeshow sized graphics, you may need more, like 1”-2.” Best practice then is to check with your printer. It’s not usually a problem to have too much bleed, only not enough bleed.
Best,
Sharon
