Whether you’re installing insulation, securing moulding, or building furniture, having the proper size staples on hand is crucial for success. But with the array of wire gauge sizes and staple crown options, how do you determine the right staple specifications? This blog post will break down the uses for different staple sizes, with a focus on 20 gauge staples. We’ll look at crown vs. flat staples, wire diameter, and recommendations for 20 gauge 7/16 crown staples and 20 gauge wide crown staples.
Understanding Staple Wire Gauges
The gauge or diameter of the staple wire affects both its strength and size. Typical wire gauges for staples range from 15 gauge up to 23 gauge. Lower gauge numbers indicate thicker wire, while higher gauges are thinner. Heavier gauge staples like 15 to 18 have greater holding power for structural work. Medium gauges around 20 strike a balance of strength with smaller size. And thinner 23 gauge works for ultra-delicate tasks.
What is A Staple Crown?
Another key distinction for staples is the shape of the crown, or top of the staple. Flat crown staples simply have a flat top profile. They slide in easily but have less holding ability. Round crown and concave crown staples have curved tops to grip material. Wider crown staples maximize this gripping surface area. The crown depth also varies, with deeper crowns providing more holding strength. Consider both crown width and depth for your project’s needs.
Choosing the Best 20 Gauge Staple Size
A versatile middle-of-the-road option, 20 gauge staples work well for a variety of indoor applications. At a 0.035″ wire diameter, 20 gauge staples are thick enough for solid holding power. Yet the thinner profile leaves smaller holes and causes less splitting in delicate wood.
Some benefits of selecting 20 gauge staples include:
- Ideal for trim carpentry, furniture assembly, and cabinetry
- Hold well in softwoods like pine without splitting
- Thin wire reduces the visible hole size
- Works with electric and pneumatic staplers
- Provides greater precision than heavier staples

When to Use 20 Gauge 7/16″ Crown Staples
A versatile and popular size, 20 gauge staples with a 7/16″ round crown are suitable for:
- Installing door and window casing trim
- Securing decorative baseboard and crown molding
- Assembling furniture frames and upholstery
The round crown spreads holding pressure to keep trim and molding tightly affixed to walls and furniture frames. The 7/16″ crown width gives excellent gripping power without being overly bulky. And the 20 gauge diameter makes these staples thin enough to conceal within trimwork.
Applications for 20 Gauge Wide Crown Staples
For even greater holding strength, 20 gauge staples with a wide crown around 1″ provide extra gripping surface. Use wide crown 20 gauge staples for:
- Attaching insulation like fiberglass batts
- Securing housewrap and roof underlayment
- Fastening weather stripping or house siding
- Upholstering thick fabrics
The wider crown distributes stress over more material to resist pulling loose. The 20 gauge wire resists bending but avoids excess bulk. Use wide crown staples when securing heavier materials or working with softwoods prone to cracking.
Sturdy Enough for the Job Yet Precise Enough for Detail Work
With the right balance of strength and finesse, keep 20 gauge staples handy for a variety of DIY projects. Consider crown width based on gripping needs. And choose shorter lengths under 1/2″ for precision in tight spaces. Follow these staple selection tips, and you’ll achieve secure fastening without splitting wood or marring surfaces. Happy stapling!
