This has been designed for a 15.75" x 33" table top retractable banner.
 
This is a digital download, NOT an actual banner.  
 
Download does not include a QR Code, or specific contact information.  The watermarked example image is to illustrate where you can add that info once you upload it to an online printer such as GotPrint.  There is a large file size (higher resolution but you may need to reduce the file size too upload too some online printer) or small file size (will upload to online printers but clarity is not quite as good).
