Container Size Matcher: Selecting the Perfect GHS Label

One Size Does Not Fit All

GHS labeling is not just about content; it's about legibility. A label that is too small to read is non-compliant. A label that is too large for a vial will crinkle and peel. The 2026 HCS update provides specific flexibility for small containers, but for standard sizes, you must follow readability guidelines.

Standard Container Sizing Guide

1. 55-Gallon Drum

Recommended Size: 8.5" × 11" or A4.

Why: The pictogram must be large enough to be seen from a distance. Text should be at least 14 pt font.

2. 5-Gallon Pail

Recommended Size: 5" × 7" or 4" × 6".

Why: Fits the side panel without wrapping around the curve, which can obscure data.

3. Spray Bottle (32 oz)

Recommended Size: 3" × 5".

Why: Standard secondary container size. Ensure it is water/solvent resistant.

4. Small Containers (≤ 100ml)

New Rule: You can use a reduced label (Product ID, Signal Word, Pictogram, Mfr Info) if a full label is infeasible.

5. Very Small Containers (≤ 3ml)

New Rule: Product Identifier ONLY. Full info must be on the box.

The Contrast Rule

OSHA requires that the label have high contrast. The pictogram must be a black symbol on a white background with a red frame. Do not print "faded" labels. If your printer is running out of red ink, the labels are non-compliant.

By matching the label size to the container, you ensure that the safety message is delivered effectively every time.
