Tissue paper GSM means grams per square meter. It measures paper weight per unit area, not thickness or the number of layers. Buyers should choose GSM alongside ply, fiber composition, product performance, and converting requirements. A higher GSM does not automatically mean better tissue.
Facial tissue and commercial hand towels serve different purposes. A paper weight that suits one product may not deliver the right result for another.
Understanding GSM helps buyers compare specifications, evaluate samples, and request more accurate quotes.
What Does GSM Mean in Tissue Paper?
GSM expresses grammage in grams per square meter. Suppliers may also use the term “basis weight,” so confirm the unit and whether the measurement applies to a single ply or the complete product.
One square meter of 18 GSM tissue weighs 18 grams.
Before comparing quotes, confirm whether the stated GSM applies to:
- One layer of base tissue.
- The combined layers of a finished product.
This distinction matters when buying multi-ply tissue. A description such as “18 GSM, 2-ply” needs clarification if the supplier has not specified the measurement basis.
ISO 12625-6:2016 provides a test method for determining the grammage of tissue paper and tissue products. Ask suppliers which method they use when comparing test reports.
What Is the Difference Between GSM, Ply, and Thickness?
GSM measures paper weight per area, ply describes the number of layers, and thickness measures the sheet’s physical thickness. These properties are related, but they are not interchangeable.
| Specification | Meaning | What Buyers Should Confirm |
| GSM | Grams of paper per square meter | Whether the figure applies per ply or to the finished product |
| Ply | Number of paper layers | The layer count and weight of each layer |
| Thickness | Distance between the sheet’s surfaces under specified test conditions | The measurement method and result for the proposed grade |
Two layers of 16 GSM tissue have a nominal combined paper grammage of 32 GSM. This assumes equal sheet areas and excludes added materials or changes during converting.
However, the combined grammage does not tell you the finished thickness. Tissue structure and manufacturing technology also matter. Valmet’s tissue manufacturing technology illustrates how high bulk can be achieved at low basis weights.
How Is Tissue Paper GSM Calculated?
Calculate GSM by dividing the sample’s weight in grams by its area in square meters:
GSM = Sample weight (g) ÷ Sample area (m²)
For example, a single-layer sample measuring 20 centimeters by 20 centimeters has an area of 0.04 square meters. If it weighs 0.72 grams, its calculated grammage is 18 GSM.
| Measurement | Value |
| Sample dimensions | 0.20 m × 0.20 m |
| Sample area | 0.04 m² |
| Sample weight | 0.72 g |
| Calculation | 0.72 ÷ 0.04 |
| Result | 18 GSM |
This example explains the calculation. Production quality checks require suitable equipment, sample preparation, and controlled test conditions.
If you weigh all layers of a multi-ply tissue together, the result describes the combined sample. It does not establish the individual GSM of each layer.
Does Higher GSM Mean Better Tissue Paper?
No. Higher GSM means more paper mass per square meter. It does not, by itself, establish softness, strength, absorbency, or suitability for a particular use.
Material composition and manufacturing processes also affect tissue performance. JX Papers’ research on recycled OCC pulp and its tissue applications examines pulp processing alongside properties such as strength, softness, and water absorption. GSM is one part of that evaluation.
For purchasing, the useful question is whether the proposed grade meets your product requirements.
A facial tissue buyer may prioritize hand feel and low lint. A hand towel buyer may focus on water absorption and strength when wet. Both need suitable performance, but they may select different paper specifications.
If a sample falls short, describe the problem to the supplier. “The towel tears during use” gives more useful direction than simply requesting a higher GSM.
What GSM Options Are Available for Different Tissue Products?
There is no single GSM that suits every tissue application. Available grades vary by supplier, fiber composition, ply, and finished product requirements.
JX Papers offers the following GSM and ply options for its virgin pulp and recycled pulp tissue ranges.
Virgin Pulp Tissue Specifications
| Product | Listed GSM Range | Listed Ply Options | Main Evaluation Priorities |
| Toilet tissue | 13–23 GSM | 1–4 ply | Softness, strength during use, and breakdown performance |
| Facial tissue | 10.5–18 GSM | 1–5 ply | Hand feel, lint, and strength during use |
| Hand towels | 18–40 GSM | 1–2 ply | Absorbency, wet strength, and dispensing |
| Napkins | 12–27 GSM | 1–4 ply | Feel, appearance, folding, and intended finish |
| Kitchen paper | 17–27 GSM | 1–2 ply | Absorbency and strength during wiping |
Recycled Pulp Tissue Specifications
| Product | Listed GSM Range | Listed Ply Options | Main Evaluation Priorities |
| Napkins | 13–30 GSM | 1–4 ply | Absorbency, strength, appearance, and folding |
| Hand towels | 18–60 GSM | 1–2 ply | Absorbency, wet strength, and dispensing |
| Toilet tissue | 13–28 GSM | 1–4 ply | Softness, strength during use, and breakdown performance |
These figures reflect the GSM and ply ranges provided for JX Papers’ virgin and recycled pulp tissue products. The specifications do not confirm whether GSM refers to each individual ply or the finished multi-ply product. Buyers should verify this with the sales team before ordering.
Virgin vs. recycled tissue: Both options are available across several tissue applications, but their GSM ranges differ. For example, virgin pulp toilet tissue ranges from 13–23 GSM, while recycled pulp toilet tissue ranges from 13–28 GSM. However, GSM alone does not determine softness, absorbency, or overall quality. Fiber composition, processing, and ply construction also affect performance.
Review the available tissue paper jumbo rolls and discuss which grades match your intended product.
For finished products, assess samples as customers will use them. Test toilet tissue for softness and breakdown performance, hand towels for absorbency and wet strength, and napkins for folding, appearance, and intended finish.
How Does GSM Affect Paper Consumption?
At the same area and ply count, higher GSM requires more paper mass. This affects material planning, but it does not directly determine the total cost of a finished product.
Consider two single-ply grades used to produce 1,000 square meters of tissue:
| Grade | Paper Area | Theoretical Paper Mass |
| 16 GSM | 1,000 m² | 16 kg |
| 18 GSM | 1,000 m² | 18 kg |
The 18 GSM grade uses 12.5% more paper mass for the same area.
This calculation excludes production waste, packaging, freight, and converting costs. It also assumes the same finished dimensions and layer count.
When evaluating a lower-GSM option, check whether it still meets your performance requirements. Record the quantity of acceptable finished product from the trial, along with waste and production issues.
A lower paper weight is useful only if the resulting product meets the agreed standard.
How Should Buyers Choose Tissue Paper GSM?
Choose a suitable GSM by defining the finished product, comparing samples, and confirming production performance. Use the approved result to establish a written order specification.
1. Define the Finished Product
Tell the supplier what you plan to manufacture or sell. Include the intended use, sheet or roll dimensions, ply, and packaging format.
If you are sourcing finished products under your own brand, our guide to OEM, private-label, and wholesale tissue supply explains the manufacturing arrangements and customization options to discuss.
A request for “18 GSM tissue” leaves out information needed to recommend a suitable grade.
2. Set Performance Requirements
Identify the properties that matter most. These may include softness, lint, dry strength, wet strength, absorbency, or appearance.
Provide an approved reference sample where possible. It gives the supplier a concrete example of your expectations.
3. Compare Samples on the Same Basis
Record the GSM, ply, dimensions, fiber composition, and finishing of each sample.
When comparing virgin and recycled grades, keep other specifications as similar as possible. This makes the comparison more useful.
If several properties change at once, it becomes harder to identify why one product performs differently.
4. Test the Paper in Production
Converters buy parent reels, the large rolls processed into finished tissue products. Confirm reel width, diameter, core size, and equipment requirements before arranging a trial.
During the trial, record web breaks, dust, winding issues, and waste. Hand feel alone cannot establish whether a grade will run well on your equipment.
5. Confirm the Written Specification
Before ordering, agree on:
- Target GSM and acceptable variation.
- Whether GSM applies per ply or to the finished product.
- Ply count and fiber composition.
- Reel or finished product dimensions.
- Performance requirements and test methods.
- The approved sample used as the reference.
Keeping these details together makes repeat orders easier to assess.
Frequently Asked Questions
What GSM Is Best for Toilet Tissue?
There is no single best GSM for every toilet tissue product. JX Papers lists virgin toilet tissue options at 13–21 GSM. Buyers should confirm the measurement basis, ply, and performance of the selected grade before ordering.
Is Lower-GSM Tissue Always Softer?
No. GSM alone cannot predict softness. Fiber composition, manufacturing, and sheet structure also influence how tissue feels. Compare finished samples intended for the same application.
Does Higher GSM Mean Better Absorbency?
Not necessarily. Manufacturing technology and sheet structure also affect absorbency. Compare test results obtained under the same conditions or conduct a consistent practical trial.
Can Two Tissues With the Same GSM Perform Differently?
Yes. Matching GSM does not mean matching fiber composition, ply arrangement, or manufacturing process. These differences can affect feel and performance, so buyers should evaluate more than paper weight.
What Should I Include in a Tissue Paper Quote Request?
Include the intended product, target GSM, measurement basis, ply, fiber requirements, dimensions, quantity, packaging, and delivery destination. For parent reels, add reel dimensions and converting requirements.
