How to Replace Buttons in 5 Simple Steps

Why Button Replacement Is Easier Than You Think

Button replacement is one of the most common — and most fixable — problems you’ll run into, whether you’re repairing a favorite pair of jeans, restoring a worn coat, or bringing a classic gaming controller back to life.

Here’s a quick overview of how to replace a button:

Prepare – Gather your tools (needle and thread for clothing, or a screwdriver for no-sew and electronics repairs)
Position – Place the new button exactly where the old one sat
Secure – Anchor your thread or rivet to the fabric or housing
Attach – Sew through the holes or fasten the hardware mechanism
Finish – Knot, trim, and test for a secure hold

The right method depends on what you’re fixing. Clothing buttons are usually sewn by hand. Jeans use metal rivets — many with no-sew installation. Electronics like gaming controllers involve screwdrivers, silicone pads, and careful disassembly.

The good news? None of these are as hard as they look. With over 70,000 replacement button options available on the market and kits starting under $10, getting the right part is simple. The technique takes just a few minutes to learn.

This guide walks you through every scenario — from stitching a shirt button back on to swapping out worn controller buttons on a Game Boy or DualSense.

Understanding Different Types of Replacement Buttons

Before we pick up a needle or a screwdriver, we need to know what we are working with. Buttons aren’t just “one size fits all.” In tailoring and hardware, variety is the spice of life. Choosing the wrong material or size can lead to a repair that looks awkward or, worse, fails after a single use.

Material	Best Use Case	Durability	Appearance
Metal	Jeans, jackets, heavy denim	Extremely High	Rugged, industrial
Resin/Plastic	Dress shirts, crafts, light wear	Moderate	Smooth, varied colors
Urea	High-end suits, trousers	High	Matte, professional
Natural Horn	Luxury coats, blazers	High	Unique, organic patterns

When shopping for a button replacement, you will likely encounter the Ligne (L) measurement system. This is a traditional unit where 1L is approximately 0.635mm. For example, a standard shirt button is often 16L or 18L (about 10-11mm), while a coat button might be 40L (25mm) or larger.

Common types include:

2-Hole and 4-Hole Buttons: The standard for shirts and trousers. 4-hole buttons offer more security for high-tension areas.
Shank Buttons: These have no holes on the front; instead, they have a small loop on the back. These are great for thick fabrics like coats because they allow the fabric to sit flat underneath.
Jeans Tacks: These are 17mm or 20mm metal buttons that usually require a hammer or a screw-in mechanism to install.

Choosing the Right button replacement for Jeans

Jeans are notorious for losing buttons because of the heavy stress put on the waistline. Standard sewing often isn’t enough for thick denim. This is where “no-sew” or “instant” buttons shine. These often come as two-piece metal rivets.

Modern kits feature adjustable waist tighteners that allow you to move the button position by about an inch—perfect if your favorite pair of jeans has become a bit too snug or too loose. Most of these “instant” buttons use a tiny screw and a screwdriver, making them removable and reusable.

Specialized Buttons for Suits and Coats

Tailoring a suit requires a bit more finesse. Professional tailors often use backing buttons—tiny, clear buttons placed on the inside of the garment—to reinforce the main button and prevent the fabric from tearing. For blazers, you might look for embossed crests (like a lion or anchor) in antique brass or nickel finishes to maintain that classic aesthetic.

Essential Tools for a Successful button replacement

You wouldn’t try to fix a car with a toothpick, and you shouldn’t try to fix a button replacement without the right gear. Depending on whether you are working on a silk shirt or a Nintendo Switch, your toolkit will look very different.

For Clothing Repairs:

Needle and Thread: Use a thread that matches the garment color. All-purpose polyester thread works for most cases.
Seam Ripper: Essential for removing the messy leftovers of the old thread.
Awl or Small Hammer: Used specifically for traditional metal jean tacks that need to be punched through the fabric.

For Electronics and Gaming:

Torx 6 and JIS 00 Drivers: Many devices, like the SunBell lamp or Nintendo consoles, use specialized Torx screws to prevent tampering. Using a standard Phillips head can strip these delicate screws.
Spudger or Opening Pick: These plastic tools help you pry apart plastic housings without scratching the finish.
Tweezers: Vital for handling tiny ribbon cables and silicone pads inside a controller.

How to Replace a Clothing Button in 5 Steps

Now, let’s get down to the actual work. We’ll focus on the most common task: sewing a standard button back onto a shirt or pair of slacks.

Step 1: Prepare the Fabric and Thread

First, clean the area where the old button lived. Pull out any loose threads with your seam ripper. Cut a length of thread about 30cm (12 inches) long. For extra strength, we always recommend “doubling” the thread—pass it through the needle and pull it until the ends meet, then tie them together in a thick knot. This gives you two strands of thread for every stitch.

Step 2: Position the Button

Alignment is everything. If the button is off by even a few millimeters, the fabric will bunch up when you fasten it. Look for the original needle holes in the fabric to guide you. Pro Tip: If you’ve lost the original button, check the “care label” on the inside side-seam of your shirt. Many manufacturers sew a spare button replacement right there for you!

Step 3: Secure the Base

Start from the back (the inside) of the fabric. Push your needle through to the front. This hides the knot on the inside of the garment. Pull the thread tight so the knot anchors firmly against the fabric.

Step 4: Execute the Stitch Pattern

Place your button over the needle.

For a 2-hole button: Go up through one hole and down through the other. Repeat this 6 to 8 times.
For a 4-hole button: You can use a “parallel” pattern (two straight lines) or a “cross” pattern (an X).
Create a Shank: If the fabric is thick, don’t pull the stitches too tight. Leave a little “wiggle room” so the button can move. You can even wrap the thread around the base of the stitches (between the button and the fabric) a few times to create a “thread shank.”

Step 5: Final Knotting and Finishing

Once the button is secure, push the needle to the back of the fabric one last time. Create a small loop with your thread, pass the needle through it, and pull tight to create a knot. Do this twice for safety. Trim the excess thread close to the knot, and you’re done!

Finishing Tips:

Always test the button by fastening it once before you put the garment away.
If you find the button is still “wobbly,” you might need more passes of thread.
For heavy coats, consider using a stronger “topstitch” thread.

Replacing Buttons on Electronics and Gaming Consoles

As experts in the retro gaming world, we know that a button replacement isn’t always about fashion. Sometimes, it’s about hitting that perfect jump in Super Mario or fixing a sticky trigger on a modern controller.

When a button on a console stops working, it’s usually not the plastic part that’s broken—it’s the conductive silicone pad underneath. Over years of play, these pads can tear or lose their “spring.” If your buttons feel “mushy,” it’s time for a deep clean or a full replacement. You can learn more about this in our guide on repairing sticky or broken buttons.

If your console is looking a bit dingy, you might also want to look into cleaning and restoring old console buttons to bring back that factory-fresh shine.

Professional button replacement for Gaming Controllers

Modern controllers like the DualSense v2 for the PS5 are marvels of engineering, but they are tricky to open.

Verification: Always check the FCC ID on the back of your controller. Models ending in “A” are the newer v2 versions, which have different internal clips than the launch models.
Disassembly: You’ll need to remove the black trim, pry out the L1/R1 buttons (careful—they like to fly across the room!), and unscrew the rear case.
The Fix: Once inside, you can swap out the face buttons or the silicone pads. For older tech, check our tips on fixing unresponsive buttons on Game Boy to save your childhood handheld.

Power and Volume Button Hardware Repairs

Device buttons like those on a Nintendo Switch or a SunBell lamp are often mounted directly to a circuit board. Replacing these requires a steady hand. On a Switch, the exterior plastic buttons are actually held in place by a rubber conductive pad. If your volume isn’t adjusting, you might need to remove the shield plate and heatsink (which involves dealing with pink thermal paste) to reach the ribbon cable that controls the power and volume.

Frequently Asked Questions about Button Repair

How do no-sew replacement buttons work?

These are a lifesaver for those who don’t want to deal with needles. Most “instant” jeans buttons consist of a front button with a hollow post and a back rivet or screw. You simply push the post through the denim and click the back into place or tighten it with a tiny screwdriver (often included in the kit). They are incredibly strong and can even be moved if you want to adjust your waistline.

What is the typical price for replacement kits?

You don’t need to spend a fortune. On sites like Amazon or Walmart, you can find basic button replacement kits for under $10. These kits often include 10 to 40 buttons, a storage box, and sometimes even the tools needed for installation. Specialized metal sets for tailoring or high-end suit buttons (like natural horn) might cost a bit more, ranging from $15 to $30 for a full set.

How do I measure button size correctly?

If you’re replacing a single lost button, use a ruler to measure the diameter of the remaining buttons in millimeters.

10mm to 11mm is standard for shirts.
15mm to 17mm is standard for trousers and jeans.
20mm to 25mm is standard for suit jackets and coats. If you see a “Ligne” size on a package, just remember the 0.635 conversion or look for the “mm” equivalent usually printed right next to it.

Conclusion

At Ganhos Reais, we believe that repair is an act of empowerment. Whether you are sewing a button on a vintage blazer or performing a delicate button replacement on a retro handheld console, you are extending the life of the things you love.
