If you love how comfy and cozy sweatpants or joggers feel when it’s cold out, you’ll love how great sweatshorts feel in the summer! They’re all the rage on TikTok and perfect for working out, relaxing at home, running errands, you name it. If you don’t want to spend money on them, they’re super easy to make yourself. Just cut the legs of some old sweats as short as you like and you’re done! In this article, we’ll show you how to cut perfect sweatshorts from pants (with expert tips from alterations expert and seamstress Jae Mee Kim) and, if you’re feeling ambitious, how to sew them from scratch.

Turning Sweatpants into Shorts: Quick Steps

  1. Lay a pair of sweatpants face up on a flat surface.
  2. Place a pair of shorts over them so the waistbands line up.
  3. Trace the bottom of the legs onto the paints with a fabric marker or chalk.
  4. Cut just above the trace line with a pair of sharp scissors.
  5. Hem the raw edges for a finished look (or leave them for a more rugged style).

  1. Watermark wikiHow to Make Sweatshorts
    You will be cutting these sweatpants up, so make sure that they are a pair you don't mind permanently altering. Make sure that the front of the pants is facing you. SMooth out the fabric so there are no wrinkles when you go to cut later. [1]
  2. Watermark wikiHow to Make Sweatshorts
    Find a pair of shorts that are the length you want your new shorts to be. Place them on top of the sweatpants so that the waistbands are aligned. Make sure that the front of the shorts is facing you too.
    • Alternatively, put the sweatpants on and make a mark with a fabric chalk or a washable fabric marker or pen where you want them to end, then take them off. [2] If you plan to hem the shorts, add an extra ½ to 1 inch (1.3 to 2.5 cm). It’s always a good idea to leave a little extra fabric—you can always make the shorts shorter, but you can’t make them longer!

  3. Watermark wikiHow to Make Sweatshorts
    Kim recommends using chalk for dark fabrics and a pen or marker for light fabrics. If you need to, use a ruler to make the line nice and straight.
    • If you want to hem the cuffs later for a finished look, add ½ to 1 inch (1.3 to 2.5 cm) to the cuffs.
    • Use a ruler to draw a straight line across 1 of the legs. Angle the line up towards the inseam slightly (about 15 degrees) to make the line look even when you’re wearing the shorts. [3]
  4. Watermark wikiHow to Make Sweatshorts
    Use a sharp pair of scissors for this, and make sure that you cut through both layers of fabric. [4] If you plan on leaving the edges raw, cut just above the line that you drew so that it doesn't show on the finished product. [5]
    • Alternatively, cut off the leg that you marked. Fold the pants in half, then use the cut edge as a guide for cutting the second leg off. [6]
  5. Watermark wikiHow to Make Sweatshorts
    Just like T-shirt material, sweatpants material does not fray. You can leave the cut edges of your sweatshorts raw and never have to worry about the fabric unraveling (although the edges may roll up slightly).
    • Tip: Place a drop of super glue or fabric glue on the cut edges of the seams. This will prevent the seams from splitting.
  6. Watermark wikiHow to Make Sweatshorts
    Fold the cut edges into the legs by about ½ inch (1.3 cm). Sew the hem down as close as possible to the cut edge. Use a thread color that matches your fabric and a straight stitch. [7]
    • To guide your sewing, Kim suggests marking a straight line with a ruler and chalk and following the line. She adds, “I usually double up on my thread to make it easier. Thicker thread is much sturdier, so it doesn't tear off the fabric.” (Chalk washes off, so don’t worry about it showing on your final product.)
    • Backstitch by about ½ inch (1.3 cm) when you start and finish sewing. Snip the excess thread off.
    • Not a sewer? Use fabric glue or iron-on hem tape instead. Follow the instructions on the label or packaging.

  1. Watermark wikiHow to Make Sweatshorts
    Sweatpant fabric looks similar to T-shirt fabric on the right side and fuzzy on the wrong side. You can find it in most fabric shops. Make sure that you are folding along the grain. The thin stripes that make up the knitting should run parallel to the fold. [8]
    • If you can't find sweatpant fabric, use T-shirt or jersey fabric instead.
  2. Watermark wikiHow to Make Sweatshorts
    Find a pair of loose-fitting shorts and fold them in half lengthwise. Place them on top of the folded fabric. Leave extra space at the top of the fabric, since this is where you’ll be sewing in an elastic band. [9]
    • Double the width of the elastic that you'll be using for your waistband. This is how far the shorts should be from the top edge of the fabric.
    • Make sure you have enough fabric (when folded in half) to be able to trace and cut this shape twice.
  3. Watermark wikiHow to Make Sweatshorts
    Make sure that you only cut around the side and bottom edges of the shorts. Don't cut along the top edge. Instead, extend the side edges all the way up to the top edge of the fabric. [10]
    • The extra length at the top edge of the shorts is for the waistband.
    • For easier cutting, trace the shorts first. Use fabric chalk for dark fabrics and a fabric pen or marker for light fabrics.
    • If you don't want to hem the cuffs, do not add a ½ inch (1.3 cm) seam allowance to the bottom of the shorts.
    • Since the fabric is folded, you’ll be cutting 2 identical pieces. These pieces will make up one leg of your shorts (you’ll repeat this later for the other leg).
  4. Watermark wikiHow to Make Sweatshorts
    This means the long, straight outer edge (which will become the outside seam of the leg) and the shorter straight edge on the opposite side that will become the inseam. Again, Kim recommends using a straight stitch, a matching thread color, and a ½ inch (1.3 cm) seam allowance. Backstitch when you start and finish sewing. [11]
    • Use sewing pins to hold the fabric together as you sew, if needed. Remember to take them out when you are done sewing.
    • Don’t sew the curved part that was the crotch/sew of your shorts yet. You are just doing the inseam and the outside seam for now.
  5. Watermark wikiHow to Make Sweatshorts
    Roll the bottom edge of the pant leg up and sew as close as possible to the raw edge (it’s OK that the raw edge is showing on the outside because you’ll eventually flip the pant leg right-side out). Use a straight stitch and a matching thread color, just like before. Backstitch when you begin and finish sewing, and snip the excess thread off.
    • If you don’t want to hem the legs, skip this step.
  6. Watermark wikiHow to Make Sweatshorts
    Use the shape you just finished sewing to trace an identical shape on your folded sweatpant fabric. Cut the second shape out and sew up the straight side edges (inseam and outside seam of the legs). Sew the cuff, if desired. [12]
    • At this point, you can trim the side seams down to ¼ inch (0.6 cm), or you can leave them as they are.
  7. Watermark wikiHow to Make Sweatshorts
    This makes a kind of “tube” that has the fuzzy side of the fabric on the outside and inside. The smooth sides of the fabric will be touching inside. [13]
  8. Watermark wikiHow to Make Sweatshorts
    Pull apart the fabric layers along the unsewn edge (on the same side as the inseam) so you’ve got 2 layers of fabric in each hand (1 layer from both pant legs). You’ll see this makes a “V” or “U” shape, and this will be the seam that connects the legs together (running down from the center of the waistband, through your legs, and up your bum). Start sewing at the waistband (the top edge of the fabric). Work your way along the curve, and up towards the other end at the waistband. [14]
    • Like before, use a straight stitch, ½ inch (1.3 cm) seam allowance, and a matching thread color. Remember to backstitch when you start and finish sewing.
    • Remember to remove your pins as you sew. If your sewing machine needle hits them, it could damage your machine!
  9. Watermark wikiHow to Make Sweatshorts
    Reach into the tube and grab the inside leg at the cuff. Pull the leg out to reveal a completed set of shorts! The wrong side of the fabric should be facing you. If it isn't, turn the sorts inside-out. [15]
  10. Watermark wikiHow to Make Sweatshorts
    Wrap a piece of wide (about 1 inch (2.5 cm)) elastic around your waist, then cut it where it overlaps. The color of the elastic does not matter because it will be inside the waistband. [16]
  11. Watermark wikiHow to Make Sweatshorts
    Sew the ends of the elastic together using a zigzag stitch . Overlap the ends of the elastic by about ½ inch (1.3 cm). Sew across the overlapped ends 3 to 4 times using a zigzag stitch on your machine. The thread color does not matter because it will be on the inside. [17]
    • Zigzag stitches are great for stretchy material like elastic. It lets the material stretch without straining or breaking the thread.
  12. Watermark wikiHow to Make Sweatshorts
    Slip the elastic over the still inside-out waistband of your shorts. Secure it to each of the front, back, and side seams with sewing pins. Make sure that the top edges are aligned, then sew the elastic to the shorts using a zigzag stitch and a matching thread color. [18]
    • Pull on the elastic as you sew so that it stretches to fit the waistband.
    • Remember to take the pins out as you sew to avoid damaging your machine.
  13. Watermark wikiHow to Make Sweatshorts
    Fold the waistband down so that the elastic is hidden. Sew along the bottom edge of this folded waistband using another zigzag stitch. Match the color to your fabric, and backstitch when you start and finish sewing. Snip the excess thread off when you are done. [19]
    • Turn the shorts right-side out when you’re done. They are now ready to wear!
    • Give your shorts a look over to snip any excess thread before hitting the town (or just lounging).
