The Complete Guide to Standard Curtain Lengths
Finding the perfect curtain length for your windows can make all the difference in a room. The right length can enhance the architecture, flood a space with natural light, and make a room feel complete. But how do you determine what length is just right?
You'll learn typical measurements for various window types and rooms. We'll also provide expert tips for getting the ideal length whether going custom or opting for standard sizes.
Typical Curtain Lengths by Window Type
One of the first factors in choosing curtain length is the size and shape of your windows. Here are some typical length recommendations based on common window dimensions:
Lengths for Small Windows
Smaller windows like those often found in bathrooms and laundry rooms will usually require shorter curtain lengths. Here are some standard sizes:
- 18-24 inches for windows under 3 feet wide
- 24-30 inches for windows around 36 inches wide
- 30-36 inches for windows up to 42 inches wide
These modest curtain lengths help keep the window from feeling overpowered or crowded. Allow 1-3 inches below the window sill for a balanced look.
Lengths for Medium Windows
For medium-sized windows like those typical in kitchens, home offices, and some bedrooms, the following lengths are common:
- 36-42 inches for windows under 4 feet wide
- 42-48 inches for windows around 4.5 feet wide
- 48-54 inches for windows up to 5 feet wide
These versatile mid-range lengths complement most decor styles from casual to formal. Allow the curtains to break 1-4 inches below the sill.
Lengths for Large Windows
To properly fit and frame larger windows like those found in many living rooms and master bedrooms, opt for these standard curtain lengths:
- 54-60 inches for windows 5-6 feet wide
- 60-72 inches for windows 6-8 feet wide
- 72-84 inches for windows 8-9 feet wide
- 84-96 inches for windows up to 10 feet wide
Longer curtains not only accentuate tall windows but also lend a luxurious feel. Allow 4-8 inches below the sill for ideal proportions.
Lengths for Extra Large Windows
For making a dramatic statement with floor-to-ceiling windows or two-story spaces, extra long lengths like these work beautifully:
- 96-108 inches for windows 10-12 feet tall
- 108-120 inches for windows 12-15 feet tall
- 120-144 inches for windows 15-18 feet tall
These commanding lengths ensure full coverage while allowing the curtains to puddle elegantly on the floor. Allow at least 8 inches below the sill.
Measuring and Customizing Curtain Lengths
While those typical size ranges work for most windows, precisely measuring your windows and calculating the ideal length is key for a perfect fit. Here are some tips:
Taking Accurate Window Measurements
Always measure the exact height of your window opening from the top of the frame to the sill. For width, measure each window panel separately. Note the widest and longest points.
Allowing for Proper Curtain Stacking and Pooling
Add 8-12 inches to the window height for casual styles allowing the curtain to stack attractively on the floor. For a more formal pooled look, add up to 18 inches.
Adjusting Length for Window Treatments and Hardware
If using decorative rods or finials that extend above or below the window, adjust the length to account for their height. Also allow for clearance if using cafe curtains or valances.
When to Use Custom Lengths vs Standard Sizes
Custom lengths are best for unusually sized windows or to achieve an exact floor-skimming length. Opt for standard sizes if your windows are close to a typical dimension range.
Curtain Length Considerations by Room
Beyond the window size, the function and aesthetics of the specific room should guide your curtain length selection:
Living Room Curtain Lengths
Living room curtains can range from puddled floor-length styles to sill-level lengths depending on your goals. Prioritize privacy and light control with longer styles or highlight architecture with shorter lengths.
Bedroom Curtain Lengths
Aim for blackout abilities in bedrooms with lengths nearly touching the floor. Light-filtering sheer under-curtains can be shorter. For small bedrooms, keep lengths close to the sill to avoid overwhelming the space.
Kitchen Curtain Lengths
In kitchens, choose lengths that provide privacy while still allowing light through. Hit just below the sill or puddle slightly. Avoid lengths too short to protect from splatters.
Dining Room Curtain Lengths
Make a statement in dining rooms with grand floor-puddling lengths. Or create an airier feel with sill-level lengths showcasing windows. Coordinate formality with table linens.
Bathroom Curtain Lengths
Bathrooms look best with shorter utilitarian lengths hitting the sill or just below. Choose moisture-resistant fabrics and avoid sweeping the floor. Add height with a decorative valance.
Expert Tips for Getting the Right Curtain Length
Follow these professional recommendations for choosing lengths with purpose:
Lengths for Maximizing Light and Privacy
For full coverage, choose lengths that break 6-12 inches below the sill. For filtered light, hit just below the sill. Or highlight with above sill lengths.
Coordinating Lengths for Window Pairs
Match lengths seamlessly on paired windows. Avoid one puddling while the other stops above the sill. Measure precisely and get identical sizes.
Adjusting Length to Enhance Room Height
In rooms with low ceilings, keep lengths close to the sill to maintain an open feel. For high ceilings, use floor-length curtains to define the space.
Troubleshooting Issues with Curtain Length
Too short? Add hidden weights at bottom hems. Too long? Hem to an optimal length. Gaps in coverage? Overlap panels and widen rod width.
Lengths for Specific Curtain Styles
The dramatic sweep of your curtains can complement their style:
Lengths for Casual, Relaxed Curtains
For breezy linen or cotton styles, opt for above the sill to sill-skimming lengths. Avoid overly formal floor-puddling.
Formal Curtain Lengths by Style
Formal fabrics like damask and jacquard look best in floor-length styles. Allow 8-12 inches of elegant pooling at floor level.
Maximum Lengths Before Hemming Required
Opt for 108-120 inch lengths as the maximum before requiring a professional hem to avoid bunching. Add weights for smoother drape.
Curtain Lengths to Complement Your Decor
Choose lengths that align with your overall aesthetic. Modern rooms look best with sill-height styles while traditional spaces can handle puddling.
