Some prefer classic, functional designs. Others obsess over every minute detail (I’m not pointing any fingers!). 

I’m definitely in the latter camp. What can I say? I never pass up the chance to add a bit of flair to my home design. 

So today, I’m moving past grand interiors and focusing on the details. 

Yes, we’re diving into the wonderful world of exterior trim options! Trust me, it’s exciting. 

Although the subject may seem cut and dry, there are actually DOZENS of exciting exterior window trim ideas for you to try on your home. 

From flat stock to fluted, decorative to functional, I’ve included 21 trim ideas to inspire your home design. 

What is window trim anyway?

First things first, let’s talk about why exterior window trim is so crucial. Not only does it add visual interest and character to your home, but it also serves a practical purpose too.

Window trim helps protect your windows from the elements and prevents any moisture (or critters, bleh!) from seeping in.

Trim also plays a role in insulation and energy efficiency by sealing any gaps around the window frame.

As I said, trim is seriously underappreciated!

How exterior window trim can elevate your home 

  • Harmony – Gives your home the ultimate harmony, with design continuation both inside and out
  • Under-utilized – A lesser-used design opportunity that can give your home’s exterior major star power
  • Strong aesthetic – Cements your aesthetic and highlights architectural details 
  • Color options – Who says trim has to be boring? You can absolutely use it as a fun opportunity for contrasting color
  • Functional purpose – Provides stylish functionality, protecting windows from the elements

Ready to get your exterior trim on? Use any of these exciting, aesthetic-focused trim ideas to give your home more visual interest and a cohesive look, inside and out. 

Modern exteriors

Modern home designers seek clean lines, play with contrast, and design with contemporary minimalism. And their exterior window trim follows suit!

1. Chic monochrome 

Want a modern, cool vibe? Try a flat stock trim in just one shade lighter or darker than your home. Here you can see that black windows and exterior are extra chic!

2. Ultra-slim profile

Use an ultra-thin trim made from metal or stained wood to simply outline your windows for a minimalist contrast.

3. Flush trim

Include a flat stock trim that is flush with the exterior walls, blending in for a smooth appearance. Low-contrast paint colors are also a must.

Colonial homes opt for classic choices, focusing on symmetry, bright whites, and timeless elegance. 

4. Multi-pane

For a clean look full of dimension, use multi-pane windows with grids and clean flat stock trim.

5. Elaborate headers

Pair classic white trim color with a decorative header featuring crown molding and a keystone center.

6. Contrasting shutters

Shutters give a nod to the historical beauty of colonial homes. Faux shutters give you the same look and are far easier to install. 

For extra interest, use a contrasting paint shade like navy blue, forest green, or a fun pop of mint (my fave!).

Cottage-style exteriors

Cozy and quaint with just a touch of whimsy – that’s the vibe cottage-style is looking to achieve. And, what you do around your windows will help get you there!

Eclectic design choices with natural finishes and gentle colors all work towards this desired charm. 

7. Planter boxes

Flower-filled planter boxes are the perfect addition under a window sill, bringing a bright, nature-inspired touch to the home.

Farmhouse exteriors

One of the most popular design styles in the game, the farmhouse aesthetic is charming, practical, and inviting. 

Natural wood and clean white finishings are common, with plenty of textiles to soften the overall feel. 

17. Crisp white 

A staple of farmhouse design, use bright white trim for all your exteriors (bonus points if it matches your front porch shade!).

Add coordinating board and batten shutters to your windows for a functional or decorative element.

Inspired by rural France, the provincial style mixes the charm of the French countryside with elegant craftsmanship. 

19. Classic bay window

A neutral white window isn’t much to talk about. But a white bay window? Now that’s a highlight!

This feature is inspired by the elaborate baroque style, making it a seamless addition to a provincial-inspired home.

Play with the historical elements of provincial design, using distressed or white-washed wood trim. 

I also recommend adding decorative accents or moldings for an elevated spin. 

21. Stone accents

For a truly special exterior trim idea, surround your window frame with stone surrounds. This is particularly beautiful for accent windows you’d like to feature.
