About this app

When replacing curtains, have you ever wondered, "Where should I measure the window?" or "Should I order the size based on the actual measurement?"

The Curtain Size Calculator is an app that automatically calculates the "order size (width and length from bottom of curtain rod)" using industry-standard formulas provided by curtain manufacturers and specialty stores, simply by entering the actual measurement of your curtain rail.

━━━━━━━━━━━━━━
■ Main Features
━━━━━━━━━━━━━━
【Calculation of Order Width】
Calculates the order width by multiplying the actual rail width by the "allowance coefficient."

・Tight (×1.02) / Standard (×1.03) / Relaxed (×1.05)
・Also supports multipliers for flat curtains without pleats (×1.10 to 1.40)
・For double curtains, the width per panel is also displayed.

【Calculation of Length (Length from Bottom of Curtain Rod)】
Automatically adjusts according to the window type.

* **Patio Doors/Bay Windows:** -1cm to prevent dragging on the floor (window sill)
* **Waist-High Windows:** +10-20cm (adjustable) to prevent light leakage from below
* **Sheer Curtains:** Automatically calculates -1cm from the drape length
* **Displays reference total length values ​​for A-hook/B-hook

**[Ready-Made Size Determination]**
Automatically determines whether the calculation result fits within commercially available ready-made sizes (width 100, 150, 200cm x length 110-230cm). You can see at a glance whether ready-made curtains will suffice or if custom-made curtains are needed.

**[Measurement Guide]**
Includes illustrated guides to help even first-time users measure correctly, such as "measuring from the center of the fixed runner" and "what is the bottom-of-the-hook dimension."

**[Calculation History]**
Copy and save calculation results in history with a single tap. Manage multiple windows in living rooms, bedrooms, children's rooms, etc., all at once.
