Hat Block (#51 regular oval)

#51 Hat Block

Our hat blocks are made to order, so please allow 5–7 business days for processing before shipping. Need yours sooner? Contact us to discuss availability, or browse our Misfits section for in-stock blocks!

Our #51 Hat Block is designed for milliners and hat makers looking for a standard oval profile for shaping, blocking, and forming hats.

This style features a regular oval shape, making it a versatile choice for a wide range of traditional and custom hat styles.

Each block is 3D printed for consistency and is available in multiple sizes.

⚠️ IMPORTANT SIZING INFORMATION

Our hat blocks are made TRUE TO SIZE.

The listed size is the actual circumference of the hat block.

YOU MUST ORDER ONE SIZE LARGER THAN YOUR FINISHED HAT SIZE TO ALLOW ROOM FOR THE SWEATBAND.

For example:

If you are making a finished 58 cm hat, order a 59 cm hat block.

The additional size provides the necessary allowance for the sweatband and helps prevent the finished hat from fitting too tightly.

#51 Standard Oval Profile

The #51 features a regular oval profile, designed as a general-purpose hat block shape for many common head shapes and hat styles.

This profile has a balanced front-to-back and side-to-side shape and is less elongated than our #52 Long Oval style.

If you need a more elongated front-to-back profile, please see our #52 Long Oval Hat Block.

Choosing Your Size

Measure the intended finished head size, then order the next size larger.

Finished Hat Size → Recommended Block Size

56 cm finished hat → 57 cm block
57 cm finished hat → 58 cm block
58 cm finished hat → 59 cm block
59 cm finished hat → 60 cm block
60 cm finished hat → 61 cm block

Half sizes may also be available depending on the selected size options.

Construction

Our hat blocks are 3D printed for accuracy and consistency and are designed for use with traditional hat-making and blocking techniques.

Because our blocks are made true to the listed size, we do not automatically add extra circumference for sweatbands, liners, or other finishing materials.

This allows the hat maker to select the appropriate block size for their specific project.

Returns & Incorrect Size Orders

Please carefully check both the size and profile before placing your order.

Because our hat blocks are made true to size, it is the buyer's responsibility to select the correct size and to order one size larger to allow for the sweatband.

Returns resulting from an incorrect size or style being ordered by the customer are subject to a $10 return fee.

If you are unsure which size or oval profile is right for your project, please contact us before ordering.
