The thickness of fragile paper labels can vary widely depending on the specific type of label, its intended use, and the manufacturing process. Fragile paper labels are generally characterized by being thin and lightweight. They are often designed to be unobtrusive, allowing them to adhere smoothly to various surfaces without adding significant bulk or weight.

In most cases, fragile paper labels may range from around 0.05 millimeters (mm) to 0.2 mm in thickness. However, it's essential to note that this is a general estimate, and actual thickness can be influenced by factors such as the type of paper used, the label's intended application, and the manufacturer's specifications.

For precise measurements, especially if dealing with valuable or irreplaceable items, it is recommended to use a micrometer or caliper to measure the thickness of the specific fragile paper label in question. Additionally, if the label is part of a collection or historical artifact, consulting with conservation experts or professionals experienced in handling fragile materials can provide valuable insights into the appropriate care and preservation methods.
