That is exactly what we are trying to find out here. We will compile the most important information in a comprehensive HTV size chart and discuss other essential aspects within its detailed guideline.

What is HTV?

For those of you who are unfamiliar with the term, HTV is short for heat transfer vinyl. This polyurethane material is used to prepare designs for garments or decorations.

Our detailed guideline today will be focused on clothes like t-shirts where HTV cutouts are transferred using heat. That is where the acronym comes from!

It is becoming more and more popular in the apparel industry because of its convenience. HTV is a very thin and flexible material that can be weeded out with ease. Since they can be prepared easily using any vinyl plotter or cutter machine, you can also implement any intricate design with this material.

Importance of HTV Size

Not getting the size right for HTV designs can make your final garment look quite unprofessional. For instance, if the design is oversized, it will look distorted or out of focus after being printed on the t-shirt. On the other hand, if it is too small, the entire piece will look misplaced on your clothes.

That’s why, in order to keep the appeal of your design intact, you must maintain proper sizing of these t-shirts. Especially for professionals or entrepreneurs, being careful about the measurements is crucial. Otherwise, the customers may question the integrity of your brand.

HTV Placement Tips

Always keep a ruler close to your crafting area so that you can take the measurements anytime necessary. It will help you both during the design phase and while applying the HTV cutout on your garment.

Before placing your design, fold the shirt lengthwise and iron it. Do the same by folding its top and create the crease along its armpit area. Ironing both of these segments in this way will make two lines respectively. Using them, you can then easily figure out the center of this whole area.


As you can see, use of HTV is not limited to t-shirts only. You can also make cute onesies, hoodies and more out of it if you want. The limits of creativity can be endless with this one!
