When searching for window treatments online, the specific query for 90 x 90 curtains in metres is incredibly common. This standard square dimension, often referred to as a 90cm by 90cm curtain, is a popular choice for covering large glass doors, creating dramatic feature walls with layered fabrics, or outfitting compact home offices. Understanding how to specify your requirements in metres is essential for achieving the perfect fit and avoiding common ordering mistakes.
The 90 x 90 size strikes an effective balance between coverage and practicality. It is large enough to frame a window or doorway elegantly, providing ample light control and privacy, yet remains a manageable size for most domestic settings. This dimension is frequently requested for bi-fold doors, sliding patio doors, and as panels in bay window configurations. When you request 90 x 90 curtains in metres, you are typically looking at a single large panel or a pair of panels designed to stack neatly to one side, ensuring the opening remains unobstructed.
Converting this standard size into the total fabric required in metres is a critical step in your ordering process. Unlike ready-made curtains sold in fixed widths, made-to-measure items are sold by the running metre, meaning the price is based on the length of fabric used. To determine your needs, you must decide on your preferred finished drop. For example, if you have a 2.4-meter ceiling height and want a 20cm hem, your drop would be 2.2 metres. You would then order 2.2 metres of fabric to create one panel. For two panels, you would double this amount to 4.4 metres, assuming you are not using a wider fabric that allows for gathering within a single width.

| Ceiling Height (m) | Finished Drop (m) | Fabric for 1 Panel (m) | Fabric for 2 Panels (m) |
|---|---|---|---|
| 2.4 | 2.2 (20cm hem) | 2.2 | 4.4 |
| 2.6 | 2.4 (20cm hem) | 2.4 | 4.8 |
| 2.8 | 2.6 (20cm hem) | 2.6 | 5.2 |
Your choice of fabric dramatically alters the final appearance and functionality of your 90 x 90 curtains. A lightweight linen will create a relaxed, breezy look with gentle movement, requiring less fabric volume to achieve the desired fullness. Conversely, a heavy velvet or tweed will hang with more structure, demanding a greater amount of fabric to achieve a rich, luxurious drape. Always discuss the weight and texture of the material with your supplier, as this affects the total weight per metre and can influence the final cost of your project.
Fullness is the secret to creating curtains that look substantial and hang beautifully. Most suppliers recommend allowing at least 2 to 2.5 times the width of the finished panel for the total curtain width. For a 90cm wide panel, this means you need roughly 180cm to 225cm of total fabric width. Achieving this often requires multiple drops of fabric sewn together horizontally. Furthermore, factor in hems—typically 20cm for the bottom and 5cm for each side—when calculating your final metre requirements to ensure the panel hangs at the exact 90 x 90 size you specified.

Because calculating 90 x 90 curtains in metres involves multiple variables—drop, fullness, fabric width, and hems—it is highly recommended to consult with a professional or a detailed online calculator before placing your order. Clearly communicate your desired stack width (how much space the curtains should occupy when open) and your preferred heading style (pencil pleat, eyelet, or tab top). A precise specification provided to a skilled tailor or curtain maker ensures you receive a product that fits perfectly and delivers the aesthetic you envision without unnecessary waste or cost.
