Written By: Founder & CEO of Elizabeth Shutters

Whether your home is a classic inspired by Frank Lloyd Wright, a stately Colonial, a breezy Ranch, or a thoughtful blend of influences gathered over time, the right shutter style does more than complete the window.

It enhances the architecture. It balances proportion. It improves light, privacy, and livability. When selected thoughtfully, shutters feel as though they were always meant to be there.

This guide will help you:

• Identify your home’s visual DNA
• Understand how the floor plan influences shutter choice
• Select louver size with confidence
• Choose panel configurations that support both function and beauty
• Use color intentionally to reinforce — or dramatically elevate — your architecture

Think of this as both inspiration and specification. A design conversation between your home’s history and how you live in it today.

Foundational Design Rules

Before identifying architectural style, it’s important to understand the structural principles that guide every successful shutter decision. These rules apply across all homes — traditional, transitional, and modern alike.

Louver Size

Louvers are typically available in 2.5”, 3.5”, 4.5”, and 5.5” widths.

• Smaller and skinnier windows (2’x2’, narrow sidelights, doorlites) → 2.5” louvers
• Mid-sized windows (3’x5’, 4’x6’) → 3.5” or 4.5”
• Large rectangles and picture windows → 4.5” or 5.5”
• Traditional homes → generally 2.5”
• Modern and open-concept homes → 3.5” minimum, often larger
• Louver size should remain consistent throughout the home whenever possible

The larger the room and the cleaner the architecture, the larger the louver can be without feeling visually busy.

Material Guidance

This is the part many brands gloss over, but it directly affects how shutters fit, how tight the light gaps are, how well they insulate, and how they hold up over time.

Pecking order of materials (best to most limited):

Whole Basswood

• Best overall
• Combination of the lightest and strongest material available
• Produced properly, has the tightest tolerances between pieces and between shutter panels and frames (best insulation, smallest light gaps)
• Available in a multitude of frames, hardware and custom shapes
• Fewest open end grains to protect against moisture damage
• Can be adjusted or tuned over time
• Ideally suitable for both painted and stained shutters in any color, color match, window shape or size

Finger-jointed Basswood (often marketed as “Solid Basswood”)

• Light, strong and very straight
• Can achieve tight tolerances and consistent light gaps
• Can be adjusted or tuned over time
• Less expensive to produce than whole basswood
• Available in a multitude of frames, hardware and custom shapes
• Generally not stainable (can look odd)
• Suitable for painted shutters, paint matches, and custom shapes/sizes

Synthetic (co-extruded blends, aluminum/wood blends, or solid synthetic)

• Weaker and heavier than basswood, but generally waterproof
• Generally few/one paint color available
• Few frame and hardware styles
• Some custom shapes may be available
• Difficult or impossible to repair
• Not stainable
• Tends to have the biggest tolerances and poorest insulation
• Ideally suitable for painted shutters in high moisture environments with standard windows/sizes

Composite

• Weakest and heaviest
• Needs to be “overbuilt” to support itself
• May be water resistant depending on wood pulp content
• Few frame and hardware styles
• Custom shapes generally unavailable
• Generally not adjustable, repairable or stainable
• Ideally suitable for temporary uses and tight budgets

Panel Configurations

SWINGING SHUTTERS

• Most common style for windows
• Maximum width of a single panel is typically 36”
• Windows 37”–72” wide typically use two panels
• Require the most interior clearance
• Wider openings can use T-posts
• Preserve views when opened fully

FOLDING SHUTTERS

• Accordion-style panels
• Ideal for wide spans and sliding glass doors
• Require less wall clearance than swinging panels
• Slightly reduce full view when stacked

SLIDING SHUTTERS

• Very rarely used on windows
• Reserved primarily for:
  • Sliding glass doors
  • Room dividers
  • Barn-door style applications

DOUBLE HUNG, SPLIT RAIL, MID-RAIL, OR SPLIT TILT BAR SHUTTERS

Top and bottom sections operate independently (depending on the build), making them ideal for privacy with natural light — especially popular in first-floor rooms and bedrooms.

Quick definitions (so this stays practical):

• Double hung: top and bottom sections open/close independently.
• Split rail: a visible rail divides the shutter, often supporting independent top/bottom operation.
• Mid-rail: a structural rail used for strength and/or alignment with window proportions (can be aesthetic, structural, or functional depending on configuration).
• Split tilt bar: allows separate control of the top and bottom louvers (privacy below, light above) without forcing the entire panel to move together.

PICTURE WINDOWS

Typically use swinging or folding shutters.

Shutter Configurations for Common Window & Door Types

These are the most common openings we design around, and the cleanest ways to cover them. (Think of these as “best-practice starting points,” not rigid rules.)

How to read the shorthand below:

• / = two panels meeting in the center
• // = four panels (two per side)
• */* or // = three-panel layouts (used when widths/clearances demand it)
• T = T-post break for wide spans (creates better fit and operation)

3’ x 5’ Rectangle (center opening slides or swings)

• /
• //

4’ x 6’ Rectangle (center opening slides or swings)

• /
• //
• */*
• //

6’ Sliding Glass Door

• /
• //
• */*
• //
• Or sliding shutters with two or three panels on an overhead track
• May alternatively use a T-post at the 2’ or 4’ point to create:
  • /T\
  • /T/

6’ Sliding Glass Door with Sidelights

• \ / /
• \ // /

8’ Sliding Glass Door

• //
• */*
• //
• Or sliding shutters with two, three, or four panels on an overhead track
• May alternatively use a T-post at the 4’ (center) point to create:
  • /T/

Color Guidance

Color is architectural language.

• Very traditional homes (Colonial, Federal, Georgian, Cape Cod) look most authentic in white
• Modern Farmhouse looks especially strong in black (often matching black window frames)
• For drama — in both traditional and modern homes:
  • Deep red
  • Navy and cobalt
  • Slate blue
  • Dark green

Color should either reinforce the home’s heritage — or intentionally elevate it.

Identifying Your Home’s Style

Many homes are hybrids. If your home reflects more than one category, lean toward the architectural influence that feels strongest in its structure and window proportions.

Founder’s Perspective

When shutters feel perfectly at home, it’s because:

• The louver scale matches the room scale
• The panel configuration respects the window width
• The color supports the architecture
• And the entire home speaks in one consistent visual language

Shutters are not an afterthought. They are architectural decisions.
