Step 1: Gather required tools and prep windows
Measuring for inside mount blinds requires precision and the right preparation. Before you start, you will need to collect specific tools and set up your window area to ensure an accurate measurement process. Getting this initial stage right sets the foundation for a perfect blind fit.
First, gather your essential measurement tools: a reliable steel measuring tape (ideally calibrated for accuracy), a sharp pencil, and a notepad or measurement recording sheet. Avoid using fabric measuring tapes or rulers which can stretch or provide imprecise readings. Clean the window frame thoroughly, removing any dust, cobwebs, or debris that might interfere with your measurements. Check that the window jamb is clear of obstacles like decorative molding or protruding hardware that could impact your blind installation.
Measure carefully and systematically. Start by checking the width at three points inside the window frame: top, middle, and bottom. Record the narrowest measurement to ensure your blinds will fit correctly. For depth, confirm you have at least 2.5 inches of space inside the window frame to accommodate an inside mount blind. This preparation guarantees a professional looking result that fits seamlessly into your window.
Pro tip: Always measure twice and write down each measurement immediately to prevent potential errors or forgotten numbers.
Step 2: Identify mounting depth and obstructions
Successfully installing inside mount blinds requires more than just taking measurements. You will now focus on understanding the specific characteristics of your window that could impact blind installation. This critical step ensures you can determine whether inside mounting is feasible and how to approach potential challenges.
Carefully examine your window frame to identify potential installation obstructions. Look for window handles, locks, decorative molding, or other hardware that might interfere with the blind’s mounting. Measure the mounting depth precisely by determining the distance from the interior wall surface to the window glass or frame. Most inside mount blinds require a minimum of 2.5 to 3 inches of depth to function correctly. Pay special attention to window stops, sills, and any protruding elements that could prevent a smooth installation.
If you encounter limited mounting space or significant obstructions, you may need to consider alternative mounting options. Take detailed notes about each potential interference and their specific measurements. This information will help you make an informed decision about whether inside mounting is appropriate or if an outside mount would be more suitable for your window.
Compare inside mount with outside mount blind installation approaches:
| Feature | Inside Mount | Outside Mount |
|---|---|---|
| Aesthetic | Seamless, built-in look | Covers frame, bold appearance |
| Space Needed | 2.5-3 inches depth | Minimal, outside frame |
| Obstruction Tolerance | Sensitive to obstructions | Easily avoids obstacles |
| Customization | Requires precise sizing | More flexible on size |
| Light Gap Control | Minimal side gaps possible | May cover gaps better |
Pro tip: Use a flashlight and mirror to inspect hard to see areas of the window frame for hidden obstructions that might not be immediately visible.
Step 3: Measure window width at three points
Accurate measurement is the foundation of a perfect inside mount blind installation. In this critical step, you will learn how to precisely measure your window width to ensure a flawless fit that looks professional and functions smoothly.
Take your steel measuring tape and measure width systematically at three distinct points inside the window frame: top, middle, and bottom. Start at the left inner edge and extend your tape measure to the right inner edge for each measurement. Record each width measurement carefully, paying close attention to any variations. Windows are rarely perfectly square, so these three measurements will reveal any subtle irregularities that could impact your blind installation.
Always record the narrowest measurement as your official window width. This approach guarantees that your blinds will fit correctly without binding or leaving gaps. If the differences between measurements are significant more than 1/4 inch, you may want to consult a professional or consider custom sizing to accommodate your window’s unique shape. Understanding these nuanced measurements will help you make informed decisions about your inside mount blind selection.
Pro tip: Wear reading glasses or use a magnifying glass to ensure you read the measuring tape precisely and avoid potential measurement errors.
Step 4: Measure window height from top to sill
Measuring window height accurately is crucial for achieving a perfect inside mount blind installation. This step will guide you through the precise process of determining your window’s exact vertical dimensions to ensure a seamless and professional result.
Prepare to measure window height systematically by positioning your steel measuring tape at the very top inside edge of the window frame. Carefully extend the tape downward to the window sill, making sure to measure at three distinct points: left side, center, and right side of the window. Each measurement is important because window frames are rarely perfectly uniform. Some areas might have slight variations due to settling, construction irregularities, or previous modifications.
Always record the shortest height measurement as your official window height. This conservative approach prevents potential issues with blind fitting and ensures smooth operation. If you notice significant variations between your measurements more than 1/4 inch differences you may want to consult a professional or consider custom sizing options. By taking multiple measurements, you create a comprehensive understanding of your window’s true dimensions.
Pro tip: Hold your measuring tape straight and taut to prevent sagging or angled measurements that could lead to inaccurate readings.
Step 5: Verify and record measurements for accuracy
With your initial measurements complete, the next critical phase involves thoroughly validating and documenting your window dimensions. This step transforms your raw measurements into reliable data that will guide your blind selection and installation process.
Apply precise measurement verification techniques by methodically reviewing each recorded dimension. Cross-reference your width, height, and depth measurements at different points to confirm consistency. Create a dedicated measurement worksheet where you can clearly document the exact numbers for width, height, and depth at each location top, middle, and bottom. Circle the smallest measurement for both width and height as these will determine your final blind size. Pay special attention to any variations between measurements that might indicate window frame irregularities.
Keep your measurement worksheet organized and legible. Include the date of measurement, window location, and any specific notes about unique characteristics or potential installation challenges. Consider taking digital photographs of your window and attaching them to your measurement documentation as an additional reference. This comprehensive approach ensures you have all the necessary information when selecting and ordering your inside mount blinds.
Pro tip: Use a pencil instead of a pen when recording measurements to allow easy corrections if needed.
Here’s a summary of critical measurement steps and the main objective for each:
| Step | Key Action | Purpose |
|---|---|---|
| Gather Tools | Collect precise measuring tools | Ensure measurement accuracy |
| Identify Obstructions | Check for depth and hardware | Confirm suitability for inside mount |
| Measure Width | Measure at top, middle, bottom | Detect window irregularities |
| Measure Height | Check left, center, right points | Account for frame variations |
| Verify & Record | Organize data, photo reference | Prevent errors, aid blind selection |
