When it comes to sewing and pattern drafting, accurate measurements are the foundation of a perfect fit. Among the essential measurements is the armhole, a critical element for ensuring your garments feel comfortable and look polished. Whether you’re a beginner, intermediate, or advanced sewing enthusiast, mastering the art of taking an armhole measurement is key to elevating your sewing game.
In this blog, we’ll guide you step-by-step through how to measure the armhole correctly using a flexible measuring tape. Let’s get started!
What Is the Armhole Measurement?
The armhole measurement is the circumference of the opening where your arm passes through a garment. This measurement helps you create sleeves and bodices that fit snugly without restricting movement. It’s especially important for garments like dresses, blouses, jackets, and shirts.
What You Need
- A flexible measuring tape
- A mirror (optional, but helpful if measuring yourself)
- A notebook or device to record your measurement
Step-by-Step to Taking an Armhole Measurement
1. Wear a Fitted Top
Start by wearing a snug but comfortable top. Avoid loose or bulky clothing that might interfere with your measurement. If possible, wear the type of undergarment you’ll use with the final garment.
2. Relax Your Arm
Stand or sit in a relaxed position with your arm resting naturally by your side. Avoid tensing your muscles or lifting your arm unnaturally.
3. Position the Measuring Tape
Take your flexible measuring tape and:
- Place one end of the tape at the top of your shoulder, where the shoulder seam of a garment would naturally sit.
- Guide the tape down the front, under your armpit, and back up to meet the starting point on your shoulder.
Ensure the tape hugs the body snugly without digging into the skin. It should be neither too tight nor too loose.
4. Check the Fit
Use a mirror or ask someone to help ensure the measuring tape lies flat and isn’t twisted. Double-check that the tape has captured the natural curve of the armhole accurately.
5. Record the Measurement
Note the number where the tape overlaps. This is your armhole measurement. Write it down immediately to avoid forgetting.
Tips for Accurate Armhole Measurements
- Measure Both Sides: While one side is usually sufficient, measuring both armholes can help detect any asymmetry.
- Stay Relaxed: Tension in your arm or shoulder can distort the measurement.
- Repeat for Accuracy: Measure at least twice to confirm your numbers.
- Use a Friend: If you’re new to sewing or find it difficult to measure yourself, having someone assist you can improve accuracy.
Common Mistakes to Avoid
- Measuring Over Bulky Clothing: This can add extra inches and result in an oversized fit.
- Pulling the Tape Too Tight: This might make the armhole too small, causing discomfort.
- Ignoring Posture: Slouching or awkward angles can skew your results.
Why Accurate Armhole Measurements Matter
Poorly fitted armholes can lead to tightness, pulling, or excess fabric that disrupts the overall look of a garment. Taking precise armhole measurements ensures that sleeves attach seamlessly, bodices fit well, and the finished piece flatters the wearer’s shape.
Conclusion
Measuring the armhole may seem simple, but it’s a vital skill for any sewist. By following these steps and avoiding common pitfalls, you’ll achieve precise results that take your sewing projects to the next level. Remember, practice makes perfect, so don’t hesitate to measure and re-measure until you’re confident in your technique.
