How to cut and sew a armhole

Armhole is a very typical area where a perfect pattern and measurements help you to sew your sleeve perfectly.

If you find any difficulty in the armhole area, let me give you a detail description. In the above diagram
(measurements in inch)

  • C-D = chest loose= (chest/4)+1.5"

  • A-F = neck breadth=(chest/12)+.5"

  • F-E = shoulder breadth= 2.5 or 3.5 inches

  • E-E' =armhole length (join E to E')
Then draw two curves at the distance of one and two inches as shown in the pattern. First you need to mark chest loose then mark the neck breadth and the shoulder breadth , next mark a straight line from E to the chest loose line(CD) i.e E-E' , that gives you the armhole length and E'-D is armhole breadth.

Next thing is that you have to draw two curves at a distance of one inch and two inch. The outer curve is at a distance of two inch and thats the mark where you have to cut for the back part of the blouse. The inner curve which is at a distance of one inch is the mark for the front part and you have to cut the armhole at the inner curve. This is how you have to cut the armhole. I hope it helps you  get a better understanding.

  4. hi Thaznim,

    I've been wanting to learn sewing for years now but it was impossible. yet in my quest to learn i used to take out the stitches of a good dress trace the cutting and stitch some of my dresses. I was so happy when i came across your site. I hope I will be able to cut and sew like you do some day. But for now I would request you to provide me with drawing instructions for measurements - where exactly they r taken esp the following.

    half shoulder measurement and hand measurement

    It would b great if you had videos too.

    Thank you

  10. Dear friend,
    Your's is a very good work.
    Is this armhole cutting applicable for ladies kurta also ?

  11. hi thaznim,
    i am so excited after viewing this website.i always wish if i could sew perfect clothes which is my hobby. but i dont have any institute fromm where i can learn perfectly. but iam glad that now i can achieve much by ur help. it would be great if u can plz help me in attaching sleeve and neck neatly.

  12. I am a novice and have been told that I need to cut the shoulder of the back higher than the front and that the front of the dress must be cut wider than the back, say about an inch. This to guarantee a good fit.

    Please explain if myth or reality?

  13. what is the measurement of E-E'. I mean how much i go down to make arm hole of kurta from shoulder (a-c)

  14. Yes, I too have the same question. How do you measure armhole length - the E-E' length or the A-c length. I have a sample kurta for measurement. or how do we take the body measurement for the armhole. Does a variation in armhole measurement cause wrinkles in the Kurta?
    What should the sleeve width be ?
