Customer Measurements vs. Staff Measurements: Why Are They Different?
In the previous chapter, I shared some stories about customers who have just bought their new homes.
New house.
New keys.
A brand-new wave of excitement.
New keys.
A brand-new wave of excitement.
But when it comes to the curtains, that’s when a lot of things they never thought of before begin to pop up. And one of the most common things I encounter is this…
“Min, I already have the measurements. Here they are.”
Sometimes, customers will even bring along a piece of paper.
The width is this much.
The height is that much.
“So Min, you can calculate the quotation based on these measurements, right?”
Yes.
Actually, I can.
I am not saying the measurements you brought are wrong.
However, there is one crucial thing I always explain to my customers…
The measurements used to calculate an initial quotation based on your rough data are not necessarily the same as the actual measurements needed to produce and perfectly install the curtains in your home.
It sounds like a small matter, doesn't it? But honestly, this is exactly where a lot of problems can start.
“Isn’t it just about measuring the window?”
This is what most people tend to think.
This is what most people tend to think.
Look at the window. Measure the width. Measure the height. Done. But when I step into a customer’s home, I don’t just look at the window. I look at the entire space. I check the position of the ceiling. I check the window frames. I look at the clearance space on both the left and right sides. I check if there are any cabinets, air conditioners, doors, switches, or anything else that could obstruct the installation. I also assess the condition of any existing rails or rods if the customer plans to reuse them.
Because sometimes…
The window measurements are correct, but the curtain measurements can be completely different.
For example…
Let's say a customer provides these dimensions:
Let's say a customer provides these dimensions:
Window width: 10 feet
Height: 8 feet
Height: 8 feet
On paper, it looks straightforward. But when I visit the house, I might discover that the customer actually wants the curtains to cover almost the entire wall, not just the window frame itself. So, the required size changes. Or, they might want a ceiling-to-floor look. If that is the case, I need to evaluate the actual distance between the ceiling and the floor. How much gap is appropriate? Where should the rail be positioned? How long should the fabric drape? None of these can be accurately determined just by looking at the bare window dimensions.
Then, there are customers who measure it themselves.
I see this all the time.
I see this all the time.
“Min, I’ve measured it myself.”
And again, there is absolutely nothing wrong with trying to help get a quick price estimation. The only issue is that when we measure on our own, we usually only measure what is visibly obvious.
On the other hand, someone who is experienced in taking curtain measurements will try to visualize what happens after the curtains are hung. That is the real difference. I don't just think,
“How many feet is this window?”
I have to think:
“If the rail is installed here, how will the fabric drape?”
“If we make the curtain touch the floor, is the length sufficient?”
“When the customer opens the curtains fully, is there enough space for them to stack back neatly?”
“If we use a specific heading style, how much fabric fullness is required?”
And most importantly…
“Does this measurement actually fit the real-life structure of the home?”
Because every house is built differently.
Some houses have windows placed very close to the ceiling, while others are far below it. Some windows have thick frames. Some are attached directly to a door. Some homes come ready with a curtain box, while others don’t. You might have a built-in cabinet right beneath the window, or an air conditioner fitted right next to it.

That is why I always say…
Curtain measurements are not just about numbers.
It is about space.
“But Min, if the measurements change, will the price change too?”
This is a question I get asked quite often.
This is a question I get asked quite often.
The answer is…
It could.
Because when the actual site measurements are taken and we find that the required size is larger or different from the initial estimate, the amount of fabric, the type of rails, accessories, or installation requirements might change too. That’s why I prefer my customers to understand this from the very beginning. If you just want a rough quotation, your own measurements are perfectly fine to use as a guide. But to get the exact fit for fabrication and booking, a professional site measurement is highly recommended. I really don’t want customers to shrug it off and think,
“Oh, it’s just a tiny difference.”
Sometimes, a tiny difference on paper can create a massive headache once the curtains are up.
I’ve met customers who insisted on ordering curtains based on old or rough measurements.
When we arrived at their home…
Problems arose. The rail didn’t fit the actual layout. The curtains didn’t drape the way they had pictured. In the end, alterations had to be made. When that happens, it’s not just a stressful experience for the customer—the costs can add up too. Yet, if these things were thoroughly checked beforehand, most of these issues could have been easily avoided. That is why I never view measuring as a minor task. Measurements are one of the very first steps that dictate how successful the final outcome will be.

So, am I telling you not to bring your own measurements?
Not at all.
Not at all.
If you have measurements, bring them.
If you have floor plans from the developer or contractor, keep them handy.
If you want a rough price estimation, just pass them to me.

I am more than happy to help you estimate the cost based on that information. However, before you officially confirm your order, I strongly encourage letting us take the actual measurements on-site. I would much rather invest a little extra time at the beginning of the process… than have you face unnecessary problems after the curtains are already tailored. To me, a job well done isn't just about making beautiful curtains. A great job starts with accurate measurements, the right technical advice, and a meticulous installation. Because at the end of the day, you aren't just paying for a piece of fabric. You are paying for an experience. You want to pull your curtains open and see a home that looks flawless, elegant, and neatly tailored. You want the fabric to fall beautifully. You want the space to feel complete. And above all, you definitely don’t want to look at your newly installed curtains and say, “Wait… why does this look off?”
So, if you are currently planning to get curtains for your new home, don’t just rush into comparing prices. Think about the measurements, the structure of your space, and how the curtains will eventually be installed. Because every home has its own unique story. And I still have plenty of stories to share from my time helping homeowners settle into their spaces. In the next chapter, I want to talk about something that often seems trivial, but can completely break the final look of your curtains RAILS.
A lot of people think, “Aren't all curtain rails the same? What's the difference?” Well… that is exactly what I will be breaking down in the next chapter. Because sometimes, the fabric isn't the problem at all. The type of rail you choose can entirely dictate how your curtains look and function.
