T-shirt sizes can vary between shops, which is why we’ve created this detailed guide to help ensure your birthday shirts fit just right! At The Joyful Rebel, our shirts, including the popular birthday boy t-shirt, birthday girl t-shirt and children’s birthday t-shirts, tend to run a bit large, particularly in length. This relaxed fit is ideal for those who prefer a little extra room, but it’s important to take accurate measurements before ordering to make sure you get the best fit.

How To Measure Your Birthday T-Shirt?

To find your perfect size, we recommend starting with a t-shirt you already own and love. Lay it flat on a surface and measure the chest size by going from armpit to armpit. Next, measure the length by running your measuring tape from the top of the collar (near the neckline) down to the bottom hem of the shirt. Once you have these measurements, compare them with our size chart to find your best fit. 

Check the diagram below for further instructions on how to measure your t-shirt, and make sure to choose the right size for the most comfortable and flattering fit!

Then compare it to this chart - it's that easy!

This process is especially helpful for special occasion shirts like our birthday shirts, birthday girl t-shirts, and birthday boy t-shirts, where the right fit ensures maximum comfort for the birthday celebration. And if you’re shopping for kids, it’s even more important to get their sizes right with our children's birthday t-shirts, as kids grow quickly and their comfort is key during fun-filled birthday events.

Our designs are made to be both stylish and comfortable, so you’ll want to be sure that the fit complements the fun designs. By following these simple steps, you’ll be able to pick out the perfect shirt for any birthday event.

Please note that we are not responsible for any incorrect size selections. Since each Personalised Birthday Tshirt and Birthday shirt is made to order, we cannot offer returns or exchanges for sizing issues. To avoid any disappointment, we highly recommend checking your measurements carefully against our size chart before making a purchase. Taking the time to measure one of your existing t-shirts can help ensure you choose the correct size.
