Perfectly structured stitches can surely enhance the look of your garments and ensure durability even after daily wear and tear. If the stitches are strong, the garment will last longer than you can expect. Therefore, it’s extremely important to know the SPI (stitches per inch) for any garment in order to give them a clean look and solid feel of quality.
There is no unified answer for how many stitches per inch can ensure the durability and aesthetic of the garment. It entirely depends on the manufacturer what he thinks is suitable for the garments he makes. But there are always some standards to maintain.
In this article, we are going to uncover the perfect answer to your question.
What Is Stitch Per Inch and Why Does It Matter?
The term stitches per inch (SPI) is used to define the number of stitches in an inch. Now the question may arise: why does it matter, right? Basically, we all may not notice the stitches all the time as a consumer while purchasing any product. But subconsciously it always matters.
All textile-related products like bags, jeans, clothing footwear use stitches to enhance the beauty or craftsmanship of the product. In that case, stitches per inch always matter in terms of executing the creative vision of the designer which will later be accepted by the consumer. Even the distance from one stitch to another creates a heavy impact on the design or appearance of the garment or product. Therefore, there is no denying accepting the pivotal role of SPI in ensuring a better appearance of the product.
Ensuring Durability is another aspect where SPI matters the most. If the stitches are too close to one another it gives more seam strength. Suppose you need to decide on stitches per inch for a pair of Snickers. Now, what will you do? Will you sew the stitches closer or distant from one another? When durability is a concern for a pair of sneakers, keeping the stitches adjacent to each other will be wise for any designer. In that case, the number of stitches per inch will increase to the standards.
Also, the number of stitches contributes to seam strength, seam appearance, and seam elasticity. Therefore overlooking SIP will be a muddled mess for any designers, tailors, or garment manufacturers.
The Stitches Per Inch Numbers You Need To Know
Whether you are a hand quilter or a machine quilter, whichever quilting technique you use, you have to be very specific with stitches per inch before even you start. Take a glimpse of the perfect knitting length you need to follow in different settings and requirements.
6-8 stitches per inch: This is basically a primitive way of quilting heavy thread and utility quilts. Many denim brands still follow this range to give their products a vintage look. This number of stitches per inch is adequate to ensure proper seam strength and is highly suitable for quick sewing cycles. So if you are up for ensuring a decent seam appearance in a short span of time, go with 6-8 stitches per inch. This is the average and minimum number of stitches you need to put in an inch.
8-1o stitches per inch: This is a perfect knit gauge when the seam needs to be strong and resilient. This will also help avoid seam grinning. In addition to that, 8-10 stitches per inch can ensure better seam coverage and customized stitch appearance. This is a standard for modern jeans, trousers, and a lot of other fashion garments to make them look more classic and trendy.
10-12 stitches per inch: Too many stitches in an inch is sometimes only a waste of your labor. But to avoid seam puckering, this is the best range to put into action. It can give the best stitch quality in terms of both strength and detail quilting. If every stitch matters to you, 10-12 stitches per inch is mandatory.
Setting SPI Standards – Things You Must Remember
While setting the SPI for your product you must take your budget into account. Because, if you set higher SIP standards for the product, it will take a longer sewing cycle to complete the seam thoroughly. In that case, it will require more thread and labor which will affect your overall budget and reduce the overall production capacity of the item. The overconsumption of the thread may increase the cost of sourcing the materials.
Considering the upper mentioned factor if you have already decided to lessen the stitches per inch, wait for a second. Abating a considerable number of stitches won’t help you to cut costs. Sometimes it may affect the quality of your product as fewer stitches mean less seam strength. This can adversely affect the durability of the seam.
So, it’s recommended that, before setting the standards of SPI, know the fabrics or material of the sewn item you are going to sew. To name a few; the composition of the fabric, the suitable sewing techniques, the type of threads, and then the SIP standards.
