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.
There are many high quality, inexpensive staple guns available (both fine wire air staple guns
and electric staple / nail guns
) that use those staples. For heavier fabric you may need to use 18-19 Gauge medium duty staplers
& staples. For very fine fabric and in cases when you need to make the staples invisible we recommend narrow crown staplers
& staples which are unobtrusive. Additionally, you need to take into consideration the hardness of the wood - for hard woods you will need stronger staples that can penetrate into the wood, such as 20 or 18 gauge staples.
Staples for upholstery applications comes in different lengths, but the most popular sizes are 1/4, 3/8, 5/8, 1/2-inch leg. The thicker the upholstery material, the longer the staple will need to be. Sufficient leg-length is needed to get good penetration into the upholstery base or frame. Stainless steel staples
for outdoor furniture and also for antique furniture are available, but in more limited types and sizes. Please inquire.
