Different length and diameter size catheters may be packaged in a universal catheter tray assembly (15) that utilizes identical base trays (20). Catheter size selectors (40), which include a size indicia (41) formed therein, are snap connected to the base tray and define at least a portion of a catheter capture channel (42) with an opening width (43) corresponding to the size indicia. The universal catheter tray assembly is configured for packaging a catheter with a size corresponding to the size indicia and with any one of a plurality of tip shapes such that first and second segments of the catheter are confined in first and second catheter capture channels (42), respectively.
