Release time:2026-11-01When customizing baseball caps, do you always encounter this embarrassment?? Obviously measure the head circumference, but when you receive the hat, it either pains your temples or blows off as soon as the wind blows. The problem is not with you, but with your failure to understand the 5 key data between the version and the head circumference. Today's article explains it thoroughly. It is recommended to collect it first and then read it!?
1️⃣ Hat circumference: not as simple as going around a circle
To measure the head circumference, you need to go through 2cm above the eyebrow bone and the most convex point on the back of the head. But the hat circumference of a custom hat is usually 1-2cm larger than the actual head circumference to be comfortable.
⚠️ Note: Different versions have different balances. The stiff version needs to leave an extra 1.5cm, and the soft top version needs to leave 0.5-1 cm. For example, when proofing, Shenzhen Yasen Man Garment Co., Ltd. will adjust the circumference and volume for different versions to avoid the "one size trap".
2️⃣ Hat depth: decide whether to press the ears or not
The hat refers to the vertical distance from the top of the hat to the root of the brim. The head circumference is large ≠ the hat depth should be deep!
✅ Standard data: head circumference 54-56cm choose hat depth 16-17cm; 56-58cm choose 17-18cm; above 58cm choose 18-19cm. If the hat depth is too shallow, it will be "on the head", and if it is too deep, it will cover the line of sight. Be sure to ask the manufacturer to provide the measured value of the hat depth when customizing, rather than just reporting the head circumference.
3️⃣ The curvature of the brim: the key to affecting the shape of the face
Many people ignore this data! The brim arc is divided into flat brim, micro-arc, and deep arc.
Round face/short face: choose a deep arc (radius of about 7-8cm), and visually elongate the face shape.
? Long face/square face: choose micro-arc (radian radius 9-10cm), balance ratio.
When customizing, ask the manufacturer if they can adjust the curvature. Shenzhen Yasenman Apparel Co., Ltd. supports fine-tuning the curvature of the brim according to the head circumference data, which is a plus.
4️⃣ Adjustment band range: invisible data in the back of the head
The Velcro or buckle range of the adjustable cap is usually 50-60cm. But people with a head circumference of less than 54cm or more than 60cm must customize a fixed circumference or an extended adjustment belt.
? Key: The overlap of the adjustment belt cannot exceed 3cm, otherwise the back of the head will bulge. Confirm whether the manufacturer provides the option of lengthening the adjustment belt before customization.

5️⃣ The "dynamic difference" between head circumference and hat circumference
The static head circumference is not enough, but also depends on the dynamic difference - after wearing the hat, do the actions of lowering the head and turning the head, and the sliding of the hat circumference does not exceed 0.5cm to be considered qualified.
? Tips: When customizing, the manufacturer is required to make the basic hat circumference according to "static head circumference + 1cm", and then fine-tune the thickness of the sweat belt. For example, Yasen Man adds 0.3cm memory cotton on the inside of the sweat belt to solve the problem of "static fit and dynamic sliding".
To sum up: Customizing baseball caps is not about reporting a head circumference. Cap circumference volume, hat depth, brim curvature, adjustment belt range, dynamic difference - these 5 data are indispensable. Before customizing next time, turn this out for comparison, or communicate directly with professional manufacturers. A supplier like Shenzhen Yasenman Apparel Co., Ltd. who will help you check the data item by item can make each hat "long" on your head.?
