Upholstery Staples

Almost any fine wire and medium wire staples can be used for upholstery, depending on your fabric. 20 and 22 gauge staples are the most common staples for upholstery. #7 series staples 22 Gauge, #8 (80) series staples 20 Gauge, and T-50 series staples 20 Gauge are commonly used for these applications. Stainless steel staples for outdoor furniture and also for antique furniture are available, but in more limited types and sizes.

How to determine staple size for upholstery application

In choosing the proper staple leg length for a job, there are two basic things to consider: thickness of material to be stapled and hardness of the wood.

As a general rule, in hardwood, approximately 3/16” to 1/4” penetration into the wood is sufficient, and for softwood – up to approximately 3/8” should be sufficient. The staple should be flush with the underlying surface. However, if the staple used is not flush with the underlying surface, – we recommend the next shorter leg length for desired results.
