How window trim can transform a space
Explore the best trim ideas for any design taste, with both modern and ancient inspiration that you will love.
Looking for exterior window trim ideas? I’ve got an entire post with 21+ ideas!
Modern
A modern trim is all about clean lines with smooth, seamless finishes. Window trim is barely there, if at all!
1. Thin trim
For a minimalist, contemporary approach, try an ultra-thin flat trim made from metal or natural wood.
2. Matte black
Matte back trim would also add a sleek beauty paired with a dark wall, or white walls for high-contrast.
3. Subtle contrast
If you prefer a classic approach, try a simple flat stock trim in a subtle contrasting color.

4. Reveal trim
Finally, for an ultra-modern look, try a reveal trim; this is a thin indent in your drywall, often made from metal, that uses negative space as a clever trim idea.
Farmhouse
If farmhouse is more your speed, your window trim should be functional and natural, with a touch of warmth and charm.
5. Natural wood
Opt for classic styles like natural wood trim or white-washed wood; this is a casual approach fitting this simple-living aesthetic.
6. Extended ledge
For more visual interest, consider adding an extended ledge that doubles as a shelf or a seat.
7. Subtle design
You could also add a bit of decorative flair to white trims with a focal point. Try wooden crown moulding accents on the header.
Fun fact – the window “header” is the trim on top of your window, with the “apron” being the bottom piece of trim.
Ranch-style
Similar to the farmhouse style, ranch-style window trim is equally simplistic, with clean horizontal lines and functional styles.
8. White wood + grids
A white window made from wooden planks gives trim a classic ranch style, with matching window grids upping the ante!
9. Focal windows
Bright, natural light is a must for this aesthetic, so large, unobstructed windows with attention-drawing wide trim make a winning combination.
Other trim, including baseboards, should be minimal.
Craftsman style
In my humble opinion, we don’t hear enough about craftsman-style design! Similar to mission-style, this aesthetic focuses on woodwork. It features a lot of natural wood, robust window trim, and a built-up design.
10. Thick and flat
To achieve this architectural style, try window trim that is thick and flat, with a slightly longer header and apron. This will give your space a cohesive look.
11. Beveled edge
To kick things up a notch, install a feature header with a subtle beauty like a beveled edge; this small detail makes for a more refined design.
Provincial-style
Inspired by French architecture, provincial-style design emulates details of both sophisticated elegance and the charming simplicity of the French countryside.
In other words, it’s downright dreamy.
12. Ornate details
For a dreamy trim to match, try soft, cream-colored trim that is decorated with ornate details. Fluted trim and scalloped edges are both totally welcome for this aesthetic.
13. Natural materials
Similar to cottage-style, you can lean into rural French vibes with whitewashed or stained wood.
Colonial-style
Dating back to the early American colonies, colonial-style decor features clean lines and flat trim to represent this “modest” era.
14. Formal molding
There’s still a touch of formality in this style of trim, with crown molding headers adding an elegant look without over-designing.
15. Practical touches
Other colonial-inspired trim ideas include exaggerated window sills and practical, double-hung windows.
Greek revival
Inspired by the grandiose Greek temples, Greek revival trim often used clean white paint and is made with wide, flat boards.
16. Fine details
Fluted window trim is also common, with decorative corner blocks being an option to take your trim to the next level.
17. Elaborate touches
Bold moldings and even embedded columns can be added if you’re feeling really fancy!
Victorian window trim
Finally, Victorian window casings are a wonder in elaborate moldings, intricate floral patterns, and layered profiles for more depth and interest. Say what you will about antique design, the Victorians knew how to decorate!
18. A celebration of color
Color lovers rejoice! Victorian-style trim is one of the few aesthetics to regularly use color, and I’m here for it.

19. Playing with textiles
Purchase luxe shades or curtains as a welcome addition to any Victorian-inspired windows.
