HTV Size Chart: What You Need for Shirts and Other Things

If it’s your first time using heat transfer vinyl, it’s easy to get confused about the right size of vinyl to use to transfer your design to t-shirts and other items.

That said, choosing the right size of HTV is crucial when customizing your tees. If you use a design that’s too small or too big, you’ll end up with unprofessional results.

The following guide will help you take the guesswork out of iron-on vinyl sizing by showing you the right size to use for various items.

Why Sizing HTV is Crucial?

As we have just stated above, you’ll need to ensure you choose the right size of heat transfer vinyl when customizing your t-shirts.

This will help ensure you get professional results, whether you’re doing it as a hobby or for your clients.

What happens if you use a vinyl piece that’s too small? Well, in this case, you’ll end up making a small design with your vinyl cutter. And when you finally apply it on the t-shirt, it’ll look unprofessional. Sorry to break it to you…but such a design will not even make your tees look appealing in any way.


And if you use an oversized piece of vinyl for your substrate? This will mean cutting a larger design than what would perfectly fit on your substrate. When you wear a t-shirt or any other garment with too big design, it might make an impression that you bought the wrong size of the cloth.

For business owners, using the wrong size of HTV is a sure way to frustrate your clients and send them away.

It doesn’t matter if you’re using the latest vinyl cutting machine or the best heat press for home use, incorrect sizing will always yield unprofessional results.

If you want to get the most appealing results when customizing various items with iron-on vinyl, take time to understand the right size of vinyl to use. The proper size will translate to a design that perfectly fits in place (on the substrate surface) and brings out the desired results.

What’s The Right Size of Vinyl To Use?

Now that you understand why it’s important to use the right size of iron-on vinyl, the next thing you want to know is the right size of vinyl to use for your projects.

The RIGHT size of HTV to use simply depends on the size of the garment you’re transferring the design onto. For instance, a t-shirt meant for an adult, say an XL or XXL size, will require a bigger HTV than that worn by a kid. Likewise, you’ll need a smaller design for baby cloth such as the onesie.

Correct HTV Placement

Apart from getting the right size of design for various garments, you should also get it right when it comes to placing the design on your item.

This will help you avoid getting crooked, unprofessional results. Moreover, the correct placement will give your garments a more expensive look (for business owners).

The easiest method of placing your design correctly on a tee involves using an iron to find the center.

How to do that?

It’s easy as pie…

Start by folding your shirt in half (lengthwise) and then iron it to create a line.

Next, fold the top of your shirt down and make a crease directly underneath the armpit — iron it to create the line.

Now you should have perfect gridlines to work with to determine the center of your shirt, and hence the correct design placement.

Take the HTV design you want to apply on the tee and fold it in half (along its length) and do the same along its width.

Finally, line up the grid lines of your tee with those of your design to find the correct placement and iron it.

That’s it! You have just placed your garment on your t-shirt correctly.

Quick Tip: The style of t-shirt you’re printing on will also dictate how to place your design. For a standard style tee, place the design about 3 inches below the neckline; for a V-neck, place it about 2 inches below the neckline.


The right size of heat transfer vinyl to use mainly depends on the size of the substrate you intend to transfer your design to. The larger the substrate surface, the bigger the design.

If you use incorrect design, you’ll end up with unprofessional results. So, make sure you follow our iron-on vinyl size chart above to help you get it right on the perfect size of vinyl to use.

After you’ve found the right size of vinyl to use, make sure you correctly place it on your shirt or any other item you’re customizing. This will help you avoid crooked results that can ruin your design.
