Taiwan Concert Support Item Size Rules: How to Measure the "Within A3" Limit at Taipei Arena and Taipei Dome
Concert notices for Taipei Arena and Taipei Dome often state "posters and banners exceeding A3 size are prohibited." This guide explains how A3 area is calculated, how uchiwa fan and sash towel (hand banner) sizes compare, and how to check each show's notice before entry.
At major Taiwanese concert venues such as Taipei Arena and Taipei Dome, the organizer's entry notice frequently includes the rule "posters and banners exceeding A3 size are prohibited." This rule exists to prevent oversized support items from blocking other attendees' views or obstructing emergency evacuation routes.
"Within A3" generally refers to the standard A3 paper size, which is 297 mm × 420 mm, or approximately 1,247 square centimeters. Importantly, these rules are usually judged by area, not by side lengths. In other words, your item does not need to fit exactly within a 297 mm × 420 mm rectangle — as long as its total area does not exceed A3, it complies. For example, a round or irregularly shaped fan is fine as long as its width × height stays within this limit.
PixHub's uchiwa fan sizes both fall comfortably within this limit. The larger Jumbo size (295 × 285 mm) is roughly 67% of the A3 area, while Regular (255 × 195 mm) is about 40%. However, the specific rules for each concert are set individually by the event organizer. Always check the official notice for your particular show on the ticketing page or the organizer's social media before you enter the venue.
