Curtains Too Short or Too Long? Our Length Chart Has You Covered
Finding the perfect curtain length can be frustrating. Hang them too short and you don't get the covered look you want. Too long and they puddle awkwardly on the floor. But have no fear - our handy curtain length chart takes the guesswork out of getting it just right!
We'll walk you through everything you need to know to pick the ideal curtain length. You'll learn about standard sizes, factors that change measurements, and how to use our chart for floor to ceiling fabulousness.
Typical Curtain Lengths
First things first - a quick overview of the most common curtain lengths:
Standard Floor-Length- Description: Long enough to puddle elegantly on floor
- Length: 84 - 120 inches
- Description: Falls just above lower window frame
- Length: 36 - 48 inches
- Description: Just grazes bottom window sill
- Length: 24 - 30 inches
These measurements work for most standard height windows. But some situations call for going longer or shorter.

When to Consider Extended Curtain Lengths
Thermal Curtains
For windows where you want to maximize insulation and regulate room temperature, thermal curtains are the way to go. They're made of thick, heat-trapping fabrics and cut much longer than regular drapes.
- Purpose: Provide insulation, maintain comfortable temp
- Extended Length: 96 - 120 inches
Blackout Curtains
If you need to completely block external light, choose blackout curtains. Their special layered construction and extended length prevent any sunlight sneaking through the edges.
- Purpose: Fully block outside light
- Extended Length: 108 - 120 inches
Tall or Large Windows
For soaring floor to ceiling windows or wide picture formats, make sure you measure the exact window height instead of relying on standard sizes. And be sure to factor in any extra puddling length you prefer.
- Measure exact window height
- Add puddling for floor-length style
Curtain Length Factors
The length chart provides useful guidelines. But keep these variables in mind too:
Curtain Style
Some curtain types like grommet top or back tab affect how much length you need to account for hanging hardware at the top.
- Grommets vs. tab top vs. back tab
- Affects height needed for hanging
Window Type
Arched, bay, corner and other uniquely shaped windows require adjusted length calculations.
- Bay, corner, arched have shape factors
- Require custom length adjustments
Puddling
Do you want that sumptuous pooled look of extra fabric billowing on the floor? Factor in an extra 8-12 inches of length (or more!) depending on personal preference.
- Extra 8-12" floor fabric
- For gathered, luxe look
- Personal preference
Fabric Allowance
Don't forget to build in some extra length to account for shrinkage and hemming the bottom edge. An extra 10-20% of the total height is typical.
- Add 10-20% for shrinkage and hem
