What Does GSM Paper Mean in Crafts

If you’re new to paper crafting, you might have come across the term GSM on packaging or in craft tutorials. It can be confusing at first, but knowing what GSM means will help you choose the right paper for your projects. Whether you’re making cards, using a cutting machine, or creating paper models, GSM plays a big role in how your final piece turns out.

What Does GSM Paper Mean?

GSM stands for Grams per Square Meter. It’s a measure of how heavy the paper is. The higher the GSM number, the heavier and usually thicker the paper feels.

Think of it this way:

• 80 GSM is like standard printer paper — thin and light.
  
• 300 GSM feels like thick card stock — strong and sturdy.
  

It’s important to note that GSM refers to weight, not exact thickness. Two papers with the same GSM can feel slightly different depending on the material or finish, but GSM gives you a reliable way to compare paper types when shopping.

Why GSM Is Important for Different Crafts

GSM affects how paper behaves when you cut it, fold it, paint on it, or build something with it. Using the wrong GSM can lead to tearing, cracking, or poor results. Here’s how it impacts common crafting tasks:

Cutting Machine Performance

If you’re using a cutting machine like a Cricut or Silhouette, the GSM of the paper matters. Lighter paper (under 150 GSM) can tear easily or shift during cutting. Heavy cardstock (above 250 GSM) needs a stronger blade and slower cutting speed. Choosing the right GSM helps you get clean cuts without wasting materials.

Folding and Scoring

For paper crafts that involve folding — like making cards or boxes — GSM affects how clean your folds are. Low-GSM paper folds easily but may not hold its shape. High-GSM paper needs to be scored before folding, or it may crack. A good score line helps thicker paper bend smoothly without damage.

Painting or Stamping

If you plan to paint or stamp on your paper, GSM affects how much moisture the paper can handle. Thin paper often wrinkles, curls, or allows ink to bleed through. Medium to high GSM paper (above 200) is more stable and works better for paints, watercolors, and ink stamping.

Durability of the Finished Piece

Projects like greeting cards, gift tags, or small boxes need to hold their shape. Lightweight paper may feel flimsy or bend too easily. Heavier paper gives a more professional look and helps your project last longer, especially if it will be handled or displayed.

Different GSM Paper Weights: Common GSM Ranges in Crafting

Paper comes in many weights, but a few GSM ranges are commonly used in crafting. Each range serves a different purpose. Understanding them helps you choose paper that fits your project, tools, and techniques.

Here is a breakdown of these common ranges.

• 35–55 GSM: They are very delicate and light and usually used for tissue paper, tracing paper, and some decorative wrapping paper.
• 70–100 GSM: They are lightweight paper similar to regular printer or copy paper. Easy to fold, but not strong enough for most standalone craft projects. Good for Origami, test prints, layering, inserts, etc.
• 120–170 GSM: They are medium weight paper slightly thicker than printer paper, with a smoother and firmer feel. They usually holds shape better but are still easy to cut and fold. Good for scrapbooking backgrounds, flyers or decorative elements, envelope making, and light die-cutting.
• 200–300 GSM: They are strong and flexible cardstock commonly used in all kinds of paper crafts and work with cutting machines and scoring tools. Good for greeting cards, paper flowers, cricut/silhouette cuts, tags, and decorations.
• 310–400 GSM: They are heavy cardstock good for card bases, small boxes, journal/album covers, and display cards.

How to Choose the Right GSM for Your Paper Crafts

Choosing the right GSM depends on what you’re making and how you plan to work with the paper. Here are a few simple tips to help you make the right choice:

1. Think About the Purpose of Your Project

Start by asking: Does this project need to be flexible, or does it need to hold its shape? For example, paper flowers and origami need to fold easily, so lighter paper is best. But if you’re making card bases, gift tags, or boxes, a thicker paper gives better results and feels more durable.

2. Choose Paper That Fits Your Tools

Not all paper works well with all tools. Most home inkjet printers handle paper up to about 250 GSM. Anything heavier might jam or not feed properly, especially if the printer only has a front tray.

If you use a cutting machine like Cricut or Silhouette, check the recommended GSM range. These machines can usually handle paper up to 300 GSM with the right blade and pressure settings. However, very thin paper may tear or shift while cutting, so test settings before starting your project.

If you’re folding heavy cardstock, use a scoring tool first. This prevents the paper from cracking and gives you a clean, professional fold.

3. Pay Attention to Surface Finish, Not Just GSM

GSM tells you the weight of the paper, but not how the surface feels or reacts to ink, glue, or paint. This is important for crafts like stamping, painting, or layering.

Coated paper — such as glossy or satin finishes — often resists water and absorbs ink differently. Paint may sit on top instead of soaking in, and glue may not stick well. For these types of projects, it’s better to choose uncoated or textured paper, especially if you need good ink absorption or grip for adhesives.

Also, some high-GSM papers feel soft and smooth, while others feel stiff and rough. It depends on how the paper is made. Whenever possible, touch and test a sheet before buying in bulk.

4. Test Small Before You Buy Big

If you’re trying a new GSM or paper brand, start with a small pack. This lets you test how it cuts, folds, prints, or holds ink before committing to a larger supply. Many craft stores and online suppliers offer sampler packs for this purpose.

5. Keep a Labeled Paper Sampler

A useful tip for regular crafters is to create a small paper sampler. Collect small pieces of different paper types you use, and label each one with its GSM, surface finish (e.g. matte, glossy, textured), and notes about how it performs. This becomes a handy reference when you’re planning future projects or shopping for supplies.

Conclusion

After reading this blog, I hope you now have a general idea of what GSM means in paper. It’s one of the most useful things to understand when working with paper. You don’t need to memorize every number. Just get familiar with the ranges you use most, and test as you go. With a bit of practice, choosing the right paper will feel simple and natural.
