Finding Your Perfect Hat Size
Every Parker Thomas hat is thoughtfully crafted, meaning each shape and silhouette may fit slightly differently. To make sure you get the perfect fit, follow our detailed size guide below.
How to Measure Your Head
What You’ll Need:
A soft measuring tape
A mirror or a friend to assist
- Start at Your Forehead
Place the measuring tape across the middle of your forehead, just above your eyebrows. This is where the hat will naturally sit. - Wrap Around Your Head
Bring the tape around the widest part of your head. Make sure it goes just above your ears and sits level all the way around. - Check the Fit
Pull the tape so it feels snug but not tight—your hat should sit comfortably without squeezing. - Read the Measurement
Note the number where the tape meets back at your forehead. Always measure in centimetres for the most accurate sizing. - Double Check
Repeat the process once or twice to ensure consistency. A second person can help make sure the tape stays level and flat.
Choosing Your Fit
Think about how you want to wear your hat:
- Snug Fit: Sits firmly on your head, won’t blow off easily.
- Comfort Fit: A little looser, allowing more airflow and easier wear for longer periods.
- Tilted Fit: If you prefer to wear your hat slightly forward or back, measure where you’d like it to sit.
Head Shapes
Extra Long Oval
An extra long oval head shape is narrow side to side and longer front to back. Hats often feel tight at the forehead and back, with slight gapping at the temples. A subtle adjustment or filler along the sides can help achieve a balanced, comfortable fit.
Long Oval
A long oval head shape is slightly elongated front to back. Hats can feel tight at the front and back while leaving a small gap on the sides. A minor adjustment or hat filler along the sides usually provides a perfect fit.
Oval
An oval head shape is the most common and typically provides an even fit all around. Hats designed in a standard oval shape should sit comfortably without noticeable pressure points or gaps.
Round
A round head shape is wider side to side and shorter front to back. Hats with a rounder crown fit best, as standard or long oval shapes can feel loose at the front and back or snug at the temples.
Finding Your Size
While we offer a variety of hats in different crown and brim shapes, the head shapes can also vary. Our Fedora and Open Crown styles feature a Round Oval head shape, while the Dallas Cattleman has a Long Oval shape.
Although our sizing conversions and charts are accurate, it’s completely normal if your head shape differs slightly from the underbrim of your hat. For the most precise fit, we recommend purchasing our Perfect Fit Guide.
If you already know your measurements and head shape, you can reference the sizing chart below.
If you fall between sizes, we recommend sizing up and adding a hat filler to your order to tailor the hat to fit your head perfectly.
Common Fit Challenges
When first trying on your new hat, you may notice slight gapping in certain areas—especially if you sized up between measurements. This is completely normal and doesn’t mean your hat fits incorrectly. Every head shape is unique, and a bit of variation is expected.
Your hat should feel comfortably snug all around your head without pressure points. If you experience gapping at the front, back, or temples, we recommend using hat filler in those areas for a more secure, custom fit.
