How to Choose a Tarpaulin: Size, GSM and Fixings
Choosing a tarpaulin starts with the job you need it to do. A lightweight sheet for a short garden project has different requirements from a cover used repeatedly over stored materials. This guide explains how to choose a tarpaulin by size, fabric weight, material and fixings, using examples from our range.
1. Measure the area you need to cover
Measure both the length and width before choosing a size. If the sheet needs to reach down the sides of an object, allow for that extra distance as well. Leave enough material for your intended overlap and attachment points: a sheet matching only the top dimensions may not cover the sides.
Check the size tolerance on the individual product page. Our blue 50gsm tarpaulin lists a size tolerance of ±10%, while the silver/black 250gsm tarpaulin lists ±7%. Allow for the stated tolerance when a precise fit matters, rather than assuming the nominal size will be exact.
2. Compare GSM and material together
GSM means grams per square metre: it describes fabric weight. Use it to compare the weight of sheets, then check their material, edge construction and intended uses. A higher GSM figure alone does not tell you how long a cover will last in your particular conditions.
- Lightweight, temporary cover: the blue 50gsm polypropylene tarpaulin is described for temporary garden, camping and DIY use. It has reinforced edges and metal eyelets.
- A heavier cover: the silver/black 250gsm polypropylene tarpaulin offers a heavier fabric option, with metal eyelets spaced every metre. Its product page lists waterproof and UV-resistant properties.
Compare the full specifications before ordering. Colour and weight are useful starting points, but they should not replace checking whether the chosen product suits the job. Browse the full tarpaulin range to compare available weights and sizes.
3. Check eyelets and attachment points
Think about where you will secure the sheet before selecting it. Both examples above list eyelets at approximately one-metre intervals. Check whether that spacing works with your attachment points and whether you need additional fittings.
Our tarpaulin accessories category is a useful place to look for fixings. Choose accessories compatible with your sheet and follow their instructions. Avoid placing all the tension on a single eyelet, dragging the sheet across sharp edges or allowing it to rub repeatedly against rough surfaces.
4. Consider the shape and conditions
A flat sheet is not always the most convenient option. For stored pallet loads, compare the dimensions and design of our pallet covers as well as standard tarpaulins. Check how the cover will fit around the load and whether access is needed during storage.
For outdoor use, consider exposure to wind and rain, how the sheet will be supported and where water could collect. Inspect the cover and fixings regularly. A waterproof fabric does not make every covered arrangement watertight: gaps, seams, damage and the way it is fitted can affect the result.
Before you order: a quick checklist
- Measure the top and any sides you need to cover.
- Allow for overlap and the product’s stated size tolerance.
- Compare fabric weight, material and intended uses.
- Check eyelet spacing and suitable fixings.
- Select the correct size option on the product page.
- Review the current availability and delivery information.
