Foam Core boards come 48" x 96" so the largest size we could print would be approximately that size, scanted by a little. However, due to UPS restrictions, anything larger than 46" x 38" would need to be picked up at our offices or delivered by van to any of the 5 Boros in NYC. If you have an indoor or outdoor sign you need that is larger than the maximum size shown in the Instant Price Calculator for that product, please reach out to our Support Team to see if we can assist you with your request. Please make sure to provide as much information as possible for us to be able to get back to you quickly and with pricing if it can be done.
