Increase Sleeve Width Alteration

Increase Sleeve Width Alteration
People love making their own clothes because they get make things that fit their specific body type.  The goal is that your handmade clothes will flatter and fit better than retail clothing.  Of course, in doing so, one must have the know-how on how to make tweaks and alterations, otherwise, clothes made from commercial patterns may end up fitting just as poorly.

This tutorial shows you how to make tweaks to the the set-in sleeve in order to increase the width of the sleeve.  The end result will be the knowledge on how to adjust your sleeve pattern pieces so your sleeve will fit you just right, especially if you frequently find your sleeves too tight.  In this example, I have you add two inches of functional ease to your measurement, which is quite common for woven fabrics.  For knits, you probably don’t need this much ease.  As always, after creating an alteration, you should first make your bodice out of muslin to test the fit and see if you need to make any further alterations before using more expensive fabric.

Using the pivot and slide method, we show you how to increase the width of a short sleeve and long sleeve.  Like with the bustline, the sleeve also affects how big our armhole needs to be.  If you’re not increasing the sleeve more than 2″ total, then no further adjustment needs to be done to the bodice or the armhole.  If you find that you do need to increase by more than 2″ total, you’ll want to watch the second part of this tutorial, because we show you how to do an added extension to make up for the increase.  We also show you how to do this same extra extension for the bustline, if you also find yourself need to do a fba (or full bust alteration) that increases more than 4″ total since you are also affecting the armhole in this process and will also need to work with the sleeve.

    It would be nice to have the step-by-step instructions in print form for future reference. Especially the calculations.


Starting in 2009, the Professor Pincushion team had a vision of creating a sewing tutorial website in which beginners could learn and master the art of sewing. Our site launched in March of 2010 and we have since produced over a hundred sewing related tutorials that cover everything from sewing basics to fun and original projects. Regardless of the subject, we always strive to create HD quality videos that takes the viewer step by step through each process so that nothing is left out and the mystery behind learning to sew is revealed to all.
