Choosing Hat Styles: Making the Best Selection for You

When it comes to men’s hats, style is as much an expression of personality as it is about function. Here’s how to approach style selection:

Understanding Popular Styles

  • Fedoras & Trilbys: These hats feature indented crowns and short to medium brims. Fedoras are versatile—classic for suits and dressy casual, while trilbys are trendier with a shorter brim.
  • Flat Caps & Newsboys: Ivy and newsboy caps are snug, rounded caps with a short brim. They’re stylish yet informal, ideal for casual wear, tweed jackets, or smart-casual dressing.
  • Cowboy & Outback Hats: Recognized by their high crowns and wide brims, these are both iconic and practical for outdoor adventures.
  • Baseball Caps: Great for everyday wear, with adjustable fits, and adaptable to virtually any casual outfit.
  • Bucket Hats: Soft, wide-brimmed, and packable—perfect for sun protection and a retro-casual vibe.
  • Top Hats & Bowlers: Reserved for formal occasions, these hats make bold, vintage style statements.

Face Shape and Style

  • Round Faces: Elongating hats (like fedoras with medium brims) balance proportions.
  • Long Faces: Wider brims and shorter crowns help add width to your appearance.
  • Square Faces: Rounded hat styles like bowler hats or slouchy beanies soften angular features.
  • Oval Faces: Most styles are flattering; pick according to occasion.

Purpose and Lifestyle

  • For sun protection, go for hats with wide brims or UPF-rated materials.
  • For winter warmth, select lined hats or woolen beanies.
  • For sports or active use, moisture-wicking and lightweight caps work best.

Understanding Men’s Hat Sizing: How to Get the Right Fit

Selecting the correct size is crucial for comfort, style, and security—no one wants their hat flying off in the breeze! Most men’s hats are sized according to head circumference, measured in inches or centimeters. There are two main systems:

  • Numeric Sizes (US Standard): Runs from 6 3/4 to 8, increasing by 1/8 increments.
  • Alpha Sizes (S, M, L, XL, etc.): Each corresponds to a numeric size range (e.g., M = 7 1/8 – 7 1/4).

How to Measure Your Head


Determine Hat Size | Hats In The Belfry - mens hat size

  1. Use a soft tape measure or a piece of string.
  2. Place it around your head where a hat would naturally sit—about 1/8 inch above your ears and across the midpoint of your forehead.
  3. Hold snug but not tight.
  4. Note the measurement to the nearest 1/8 inch (or 0.5 cm). Refer to a size chart to find your ideal hat size.

Quick Reference for Common US Sizes:

Circumference (in) US Hat Size General Size
21 1/8 6 3/4 Small
22 7 Medium
22 7/8 7 1/4 Large
23 5/8 7 1/2 X-Large
24 1/2 7 7/8 XX-Large

Tip: Choose a hat that’s comfortable and slightly loose rather than tight, especially for warmer months or all-day wear. If between sizes, consider sizing up and using sizing tape for adjustments.

Material Comfort: What to Consider for the Perfect Feel

The physical comfort of a hat depends heavily on its material and craftsmanship. Different materials suit different climates, activities, and personal preferences:

  • Wool Felt: Warm, soft, and water-resistant—ideal for cooler temperatures and formal events.
  • Straw: Lightweight and highly breathable, perfect for summer and sun protection.
  • Leather: Durable and stylish, often used in cowboy or outback hats. Can feel hot in summer.
  • Cotton/Twill: Comfortable and easy to clean, used in bucket hats and baseball caps.
  • Synthetic Fabrics: Common in performance/sports hats; good for moisture-wicking and adjustability.
  • Knits (Beanies): Stretchy and warm for winter usage.

Lining and Bands: Consider hats with sweatbands or lining for extra comfort and improved fit, especially for active wear or high-heat conditions.

Outfit Matching: Pairing Hats with Your Wardrobe

A thoughtfully chosen hat can elevate your entire outfit. Match your hat style, color, and material to the occasion:

  • Formal Occasions: Wool felt fedoras, top hats, and classic flat caps pair excellently with suits or coats.
  • Smart-Casual: Flat caps, newsboy caps, and structured felt hats work well with blazers, sweaters, or business-casual attire.
  • Casual: Baseball caps, bucket hats, and beanies blend with jeans, hoodies, and t-shirts.
  • Outdoor/Adventure: Cowboy hats, outbacks, and wide-brimmed straw hats protect against the elements while matching with workwear or hiking clothes.

Color Coordination: For versatility, choose neutral hat colors—black, grey, tan, or navy. To make a statement, opt for bolder hues or prints that pick up colors in your shirt, tie, or outerwear.

Seasonal Recommendations: The Best Hats Year-Round

Hats are not just for style—they offer practical protection from the sun, cold, and rain. Here’s how to select seasonally:

Spring/Summer

Fall/Winter

  • Wool Fedoras, Felt Hats: Heavier, insulative, and great for blocking wind.
  • Beanies: Stretch knit for maximum warmth and adaptability to most casual outfits.
  • Flat Caps & Newsboys: Tweed or wool options keep you both warm and stylish.

All-Weather

  • Waterproof Outback/Cowboy Styles: For year-round protection; look for UPF (ultraviolet protection factor) labels if you’re frequently outdoors.

Practical Tips and Best Practices for Buying and Wearing Men’s Hats

  • Measure Twice: Always double-check your head size before purchasing, especially when trying a new brand or style.
  • Account for Hair: Fuller hairstyles may need a slightly larger hat size.
  • Try Before You Buy: If possible, try hats on in-store for fit and style. Online, read sizing guides carefully and select brands with flexible return policies.
  • Adjustable Sizing: Many casual hats feature internal Velcro/snapback straps or elastic—perfect for fluctuating hair length or minor size differences.
  • Breaking In: Some materials (leather, heavy felt) relax with use. If your new hat feels slightly snug, wear it for brief periods to allow gentle stretching.
  • Care and Cleaning: Follow manufacturer recommendations. Spot-clean stains and regularly dust off for felt hats; straw hats should be stored away from moisture.
  • Travel and Storage: Use hatboxes or packable hat designs for protection on the go.
  • Use Hat Sizing Tape: Foam tape strips inside the sweatband can tailor the internal fit—helpful if you’re between sizes.
  • Seasonal Storage: Store wool and felt hats in cool, dry places with gentle supports to preserve shape. Keep straw hats out of prolonged humidity.
  • Maintain Shape: For structured hats, avoid crushing or folding. Use appropriate hat supports if storing for a long period.

FAQ

  1. How do I measure my head accurately for a hat?
    Use a flexible tape measure. Place it around your head, about 1/8 inch above your ears and across your mid-forehead where the hat will sit. Hold snug but not tight, note the measurement, and compare to sizing charts.

  2. What is the average men’s hat size?
    The average size for men typically falls between 7 1/4 and 7 3/8 in US terms, which translates to a head circumference of approximately 22 5/8 to 23 inches (57–59 cm).

  3. Should I choose a hat size up if I’m between sizes?
    Yes, sizing up is often more comfortable. If the hat is a little big, you can use hat sizing tape or foam inserts to perfect the fit.

  4. How do adjustable hats compare to fitted hats in terms of size?
    Adjustable hats (like baseball caps) fit a range of head sizes using straps or elastic, offering more flexibility. Fitted hats come in specific sizes and provide a cleaner, precise look.

  5. Do all hat manufacturers use the same sizing?
    No, sizing can vary between brands and countries. Always consult each brand’s unique size chart and, if possible, check reviews regarding sizing accuracy.

  6. Will my hairstyle affect my hat size?
    Yes, thicker or longer hair may require a slightly bigger hat size for a comfortable fit, especially if you often change hairstyles.

  7. How can I adjust a hat that’s too loose?
    Add hat sizing tape, foam inserts, or a thicker sweatband inside the hat. These reduce the fit by small increments for a more secure feel.

  8. Which hat materials are best for summer and winter?
    For summer, lightweight and breathable materials like straw, linen, or cotton work best. For winter, wool, felt, and knit fabrics provide warmth and insulation.

  9. Is there a difference between men’s and women’s hat sizing?
    Men’s hat sizing is often more standardized with numeric sizing, while women’s hats may use general size labels. However, actual head measurement should determine fit in either case.

  10. How do I care for and maintain my hat’s size and shape?
    Store hats in a cool, dry place on a flat surface or using a hat form. Clean according to material (felt, straw, cotton), avoid crushing, and use proper travel storage to maintain the hat’s original shape and size.
