When making buttonholes in a kids’ knit cardigan, the general rule is to place the first and last buttonhole about 1/2 inch (about 1.25 cm) from the top and bottom of the garment2. The bottom buttonhole should be placed at least an inch away from the bottom edge of the cardigan to avoid it looking too close to the edge1.
The number of stitches between the other buttonholes will depend on the final length of the cardigan. A good rule of thumb is to place markers where you want the buttonholes to be, and then evenly space the remaining stitches between the markers3.
You can also calculate the spacing using simple math by subtracting the number of stitches for the buttonholes from the total number of stitches, and then dividing the remainder to calculate the number of stitches between each buttonhole.
It’s worth noting that the placement of buttonholes can vary depending on the design of the cardigan and personal preference. For example, traditionally, buttonholes for girls’ cardigans are placed on the right side, while those for boys’ cardigans are placed on the left side5.

Factors to Consider
When it comes to creating buttonholes in your knit cardigan, there are a few important factors to consider. These factors will not only affect the appearance of your buttonholes but also the functionality of your cardigan. By carefully considering the type of yarn, size of buttons, and gauge or tension, you can create buttonholes that are both visually pleasing and sturdy.
Type of Yarn
The type of yarn you choose for your cardigan will play a significant role in determining how your buttonholes will function. Different yarns have different levels of elasticity and stretch, and this can affect the durability and longevity of your buttonholes.
If you’re using a yarn with a high level of stretch, such as a wool or acrylic blend, you may want to consider reinforcing your buttonholes to prevent them from stretching out over time. On the other hand, if you’re using a yarn with less stretch, such as a cotton or linen blend, you may not need to reinforce your buttonholes as much.
Size of Buttons
Another important factor to consider is the size of your buttons. The size of your buttons will determine the width and length of your buttonholes, as well as the spacing between them. It’s essential to choose buttons that are proportionate to the size of your cardigan and that fit through your buttonholes comfortably.
If your buttons are too large for your buttonholes, you may have difficulty fastening and unfastening your cardigan. Conversely, if your buttons are too small, they may slip through the buttonholes too easily. Take the time to find the right balance and choose buttons that complement your cardigan’s design.
Gauge or Tension
The gauge or tension at which you knit your cardigan will directly affect the size and placement of your buttonholes. The tighter your gauge, the smaller your buttonholes will be, and the more closely spaced they will need to be.
When calculating your buttonhole placement, it’s crucial to take your gauge or tension into account. If you’re following a knitting pattern, the gauge specified in the pattern will give you a starting point for determining your buttonhole placement. However, it’s always a good idea to make a gauge swatch and adjust your measurements accordingly.
Determining the Buttonhole Placement
Once you’ve considered the factors mentioned above, it’s time to determine the placement of your buttonholes. This step is crucial to ensure that your cardigan fits comfortably and that your buttonholes align with your buttons.
Buttonhole Spacing
When determining the spacing between your buttonholes, you’ll want to ensure that they are evenly distributed along your button band. An even spacing will create a visually pleasing design and prevent any bunching or stretching of the fabric between the buttonholes.
One common guideline for buttonhole spacing is to place the first buttonhole approximately 1-2 inches from the bottom of the cardigan. From there, you can divide the remaining space evenly, leaving slightly more space between the top buttonhole and the neckband to accommodate for the curvature of the neckline.
However, it’s important to take into account the size of your buttons and the width of your button band when determining the spacing between your buttonholes. A good rule of thumb is to leave approximately two buttonhole widths between each buttonhole.
Buttonhole Placement Techniques
There are various techniques you can use to mark the placement of your buttonholes on your cardigan. One simple method is to use pins or stitch markers to mark the desired placement. You can then try on the cardigan to ensure that the buttonhole placement aligns with your body shape.
Another technique is to measure the desired placement of your buttonholes using a tape measure or ruler. This method allows for precise measurements and ensures that your buttonholes are evenly spaced. Remember to double-check your measurements and make any adjustments before proceeding with creating the buttonholes.
Standard Measurements and Guidelines
To create buttonholes that are both functional and aesthetically pleasing, it’s helpful to follow standard measurements and guidelines. These measurements can serve as a starting point and can be adjusted based on your personal preferences and the specific design of your cardigan.
Buttonhole Width
The width of your buttonholes is an essential consideration when creating your cardigan. The width should be large enough to comfortably fit your buttons through while still providing a snug fit. However, the width should not be too wide, as this can cause the buttons to slip through the buttonholes too easily.
A standard guideline for buttonhole width is to make them approximately 1.5 times the diameter of your buttons. This allows enough room for the buttons to pass through while still maintaining a secure fit. However, if you’re using thicker yarn or larger buttons, you may need to adjust the width accordingly.
Buttonhole Length
The length of your buttonholes is another crucial measurement to consider. The length should be sufficient to allow the buttons to pass through without straining the fabric. However, if the buttonholes are too long, they may become stretched out over time and lose their shape.
As a general rule, the length of your buttonholes should be approximately 1.5 times the width. This provides enough room for the buttons to pass through while still maintaining the integrity of the fabric. Be sure to measure your buttons and adjust the length accordingly to ensure a proper fit.
Button Placement
In addition to buttonhole measurements, it’s important to consider the placement of your buttons. The height of your buttons should align with the height of your buttonholes to ensure a secure and comfortable fit.
A standard guideline for button placement is to place the first button approximately 1-2 inches from the bottom of the cardigan. From there, you can evenly space the remaining buttons, leaving slightly more space between the top button and the neckband. This spacing will allow the button band to lay flat and prevent any bunching or stretching.
Calculating Buttonhole Placement
Calculating the placement of your buttonholes requires a bit of math, but it’s a necessary step to ensure that your buttonholes are evenly spaced and aligned with your buttons. By considering the total number of buttonholes needed and the cardigan’s total length, you can determine the precise placement of each buttonhole.
Number of Buttonholes
The first step in calculating buttonhole placement is determining the total number of buttonholes needed. This will depend on the number of buttons you plan to use and the desired spacing between them.
To calculate the number of buttonholes, you can divide the total length of your cardigan by the desired spacing between your buttonholes. For example, if your cardigan is 20 inches long and you want to leave 2 inches between each buttonhole, you would divide 20 by 2, resulting in 10 buttonholes.
Total Cardigan Length
Once you know the total number of buttonholes needed, you can determine the precise placement of each buttonhole by dividing the cardigan’s total length by the number of buttonholes.
For example, if your cardigan is 20 inches long and you need 10 buttonholes, you would divide 20 by 10, resulting in 2. This means that you should place your buttonholes every 2 inches along the button band.
Remember to adjust your calculations based on the specific design of your cardigan and the desired spacing between your buttonholes.

Additional Tips and Techniques
While following the guidelines and calculations mentioned above will help you create functional and visually pleasing buttonholes, there are a few additional tips and techniques you can use to enhance your buttonhole experience.
Using Markers or Pins
To ensure accurate buttonhole placement, it can be helpful to use markers or pins to mark the desired locations. This way, you can try on the cardigan and make any adjustments before creating the buttonholes.
Trying on as You Go
It’s always a good idea to try on your cardigan as you go to ensure that the buttonholes align with your body shape and the buttons fit comfortably. Trying on your cardigan at different stages of completion will allow you to make any necessary adjustments to the buttonhole placement.
Adjustments for Button Bands
When creating buttonholes, it’s important to take into account the width of your button bands. The button bands should be wide enough to accommodate the buttonholes comfortably without causing any strain or stretching.
Adjust the width of your button bands accordingly to ensure that the buttonholes are proportional and aligned with the buttons. This will create a visually pleasing design and prevent any bunching or stretching in the fabric.
Finishing and Securing Buttonholes
Once you’ve created your buttonholes, it’s essential to finish and secure them to ensure their durability and longevity. This step will prevent the buttonholes from stretching out or unraveling over time.
Reinforcing Buttonholes
One method of reinforcing buttonholes is to use a reinforcing stitch around the edges of the buttonhole. This can be done using a sewing machine or by hand. The reinforcing stitch provides added stability and prevents the buttonhole from stretching out.
Another way to reinforce buttonholes is to use a contrasting yarn or thread to whip stitch around the edges of the buttonhole. This not only adds strength but also creates a decorative edge.
Blocking the Cardigan
Blocking your completed cardigan is another crucial step in finishing your buttonholes. Blocking involves gently washing and shaping your cardigan to even out the stitches and allow the yarn to relax.
When blocking, pay special attention to the buttonholes, gently shaping them to the desired size and ensuring that they are aligned with the buttons. Blocking will help the buttonholes retain their shape and prevent any distortion.

If you prefer not to create traditional buttonholes, there are alternative closure options you can explore. One option is to use snaps or hook-and-eye closures instead of buttons. These closures can be hidden under the button band, creating a clean and sleek appearance.
Another option is to use toggles or clasps as fasteners. Toggles can create a more rustic or bohemian look, while clasps provide a more modern and streamlined appearance.
Embroidered or Decorative Buttonholes
For those looking to add a bit of flair to their cardigan, consider using embroidered or decorative buttonholes. Embroidered buttonholes can be created using various stitching techniques and threads to add a pop of color and texture.
Additionally, decorative techniques such as picot edges or lace can be used to create visually interesting buttonholes. These techniques can elevate the overall design of your cardigan and make your buttonholes a focal point.
Common Buttonhole Mistakes
While creating buttonholes may seem like a straightforward task, there are a few common mistakes to avoid to ensure a successful outcome.
Misaligned Buttonholes
One common mistake is misaligned buttonholes. If your buttonholes are not properly aligned with your buttons, your cardigan may appear lopsided or asymmetrical. Take the time to carefully measure and mark your buttonhole placement to avoid this issue.
Inconsistent Buttonhole Spacing
Another common mistake is inconsistent buttonhole spacing. If the spacing between your buttonholes is uneven, your cardigan may appear sloppy or ill-fitting. Using markers, pins, or precise measurements will help you achieve consistent spacing and a polished finish.
