How do you make an A4 envelope step by step?


Before you begin making your own envelopes, gather the following materials:



  • A4 paper


  • Scissors


  • Glue or tape



These materials are readily available at most craft stores or can be easily found online. Once you have everything you need, you are ready to start creating your own envelopes.



Step-by-Step Guide


Follow these simple steps to make your own envelopes:



  • Folding the Paper into the Envelope Shape


Begin by placing your A4 paper horizontally on a flat surface. Fold the bottom edge of the paper up to meet the top edge, creating a horizontal crease in the middle. Unfold the paper and you will have a crease line as a reference point.


Next, fold the left and right sides of the paper inward, aligning them with the central crease. This will create two flaps on the left and right sides of the paper.



Finally, fold the bottom edge of the paper up to meet the bottom edge of the flaps. This will form the bottom of the envelope. Make sure to crease the folds firmly to create sharp edges.



  • Securing the Edges with Glue or Tape:

Once you have folded the paper into the envelope shape, it’s time to secure the edges. Apply a thin line of glue or double-sided tape along the bottom edge of the side flaps. Press the flaps firmly against the bottom of the envelope to seal them in place.


Next, apply glue or tape along the bottom edge of the bottom flap. Fold the bottom flap up and press it firmly against the side flaps to seal the envelope shut.


  • Optional: Decorating the Envelope:


Now that you have a basic envelope, you can unleash your creativity and personalize it further. Consider adding decorations such as stickers, washi tape, or hand-drawn designs. You can also experiment with different paper colors or patterns to create unique and eye-catching envelopes.



Remember to leave enough space on the front of the envelope for the recipient’s address and your return address. You can either write these by hand or print them using a printer or label maker.


What size envelope can you make from A4 paper?


You can use an A4 sheet of paper to create different sizes of envelopes, depending on how you fold it and where you make your cuts. Here are instructions for making a basic envelope from an A4 sheet:


  • Fold and Trim: Take your A4 paper and fold it in half along its shorter side 


  • Fold Again: Next, fold the paper in half again along its shorter side. This will give you a folded paper.


  • Cut the Flap: On the folded end of the paper (the shorter side), use scissors to cut a diagonal line from the outer corners toward the center, stopping a couple of inches from the centerfold. This creates a triangular flap.


  • Unfold and Fold Up: Gently unfold your paper, and you’ll see a rectangular shape with a triangular flap at the bottom. Fold up the bottom third of the paper (the triangular flap), and you now have an envelope shape.


  • Secure the Edges: You can use glue or double-sided tape to secure the side edges of the envelope. Be sure not to glue the top flap shut; this is where you’ll insert your letter or card.
