Logo on packaging: features of placement and scaling
How to calculate the logo size for a specific package
The first thing to do before opening a graphic program is to determine two parameters: the dimensions of the panel on which the sign will be placed, and the printing technology. This determines everything else. The logo is not scaled "by eye" — it is tied to the width of a specific side of the packaging in percentages, not millimeters.
| Packaging type | Printing method | Recommended logo size |
|---|---|---|
| Consumer box (cosmetics, food products) | Offset, screen printing | 20–35% of panel width |
| Transport corrugated box | Flexo printing | up to 1/3 of the main side width |
| Blister, small box | Offset, UV printing | minimum 0,75 inches (≈19 mm) |
| Flexible package (doy-pak, sashe) | Flex printing, deep printing | 15–25% of the front side width |
The logic is simple: you measure the width of the side where the sign will be placed, take the percentage from the table — you get a range in millimeters. If the panel is narrow (for example, the end side of the box 60 mm), the logo will not physically fit in 20 mm while preserving the readability of the details — in that case, it is either moved to a wider side or a simplified version without small elements is used.
Minimum size: where the logo turns into a mess
Small text, thin lines and gradients in the logo — the first elements that get lost when the logo is scaled down. On screen printing and flexographic printing, thin lines (depending on the technology — from 0,1–0,2 mm) are printed with the risk of the ink bleeding; practically, this means that logo details thinner than 0,3–0,5 mm may be lost or distorted. Therefore, most logo guidelines have a version for small applications — a simplified mark without details that remains legible even at 10–15 mm.
- 20 mm — the standard minimum for the main logo on printed media;
- 10–15 mm — for the simplified/detailed version of the logo (without thin lines and small text);
- 0,75 inches (≈19 mm) — the lower limit for small packaging types such as blister packs;
- below these values, the textual part of the logo ceases to be readable by the naked eye at a distance of half a shelf.
Maximum size: why bigger doesn’t mean better
A logo cannot be enlarged infinitely, and this is not a matter of taste, but of perception. A mark occupying half of the front panel is not perceived as a premium brand, but as cheap advertising — the packaging loses the sense of the product and becomes a billboard. The upper limit is 35% of the panel width for consumer packaging and no more than one-third of the main side width for transport boxes. Anything larger visually "eats" the other design elements: the product name, ingredients, decorative elements — and forces the eye to focus only on the mark, which reduces the overall informativeness of the packaging.
Box construction: folds, flaps, glue zones
A logo that perfectly fits on a flat mockup in Illustrator can 'break' in a real box—if the designer did not account for the shrinkage form. This is one of the most frequent errors when transferring a logo from a brand book to packaging.
| Type of construction | Risk for the logo | Recommendation |
|---|---|---|
| FEFCO 0201 (classic corrugated box) | The logo falls on the flap or the area of the lid closure | Place on the central panel, leaving a 15–20 mm gap from the upper flap |
| Rigid box | The logo tears at the joint of the lid and the bottom | The logo is entirely on the lid, without transfer to the side wall |
| Flexible bag / doy-pack | The logo falls into the area of the welded seam or zip-lock fastener | A minimum 10 mm gap from the side seams |
| Foldable boxes with a center fold | The logo breaks along the fold line | Shift the mark into one of the 'flat' zones of the panel, bypassing the fold line |
The rule is simple: the logo must not cross the fold line, perforation, the gluing zone, or the tape zone at any stage of the packaging lifecycle — from printing to assembly on the conveyor. If the layout is flat but the packaging shape is three-dimensional, it is essential to check the placement on the 3D-unfold or a physical mock-up, not just on a flat file.
Margins and safety zone around the mark
The safety zone (clear space) is the distance around the logo, free from any other elements: text, illustrations, barcode, and on packaging — also from edges, tape, labels, and fold lines. The standard is no less than 10% of the logo width on all sides. This rule applies to brochures and websites, but on packaging, an additional, stricter check is added: technological tolerances.
- The margin from the packaging edge — no less than 5 mm for small formats, 10 mm for large corrugated boxes (compensating for cutting and assembly tolerances).
- The margin from the fold line or center fold — the logo must not cross the line at all; it is better to maintain a gap of at least 3 mm.
- The margin from the gluing zone and perforation — at least 10 mm; these zones often consume part of the image during machine assembly.
- Check at the place of tape or courier label application for transport packaging — the logo must not fall under it.
Top or bottom: not only aesthetics
The position of the logo on the packaging is perceived by the consumer not only as a design element, but also as a signal of the product's status. The logo placed at the top of the box — on the lid, on the upper flap — is perceived as a more premium, status-oriented placement. A logo shifted to the lower part of the panel makes the packaging visually more accessible and democratic. This should be taken into account when choosing the position: for an expensive product, the top works, for the mass segment — the bottom or center — all work to create different perceptions of price.
File formats and printing specifics
A logo for packaging is prepared and sent to the printing house only in vector format — AI, EPS or PDF with text converted to curves. Raster JPG and PNG files are not suitable for printing at all: when magnified, the edges become jagged, and thin lines and small text turn into unreadable spots, especially on seams, folds and textured materials such as kraft cardboard.
Color model for printing should be considered separately. For flexographic printing — the standard technology for corrugated boxes — there is a limitation on the number of colors: maximum 8 colors per run, and lines thinner than the recommended thickness (usually from 0,25–0,3 mm depending on the anilox roll) disappear completely. Offset printing and screen printing have more lenient tolerances, but the principle is the same: the more complex the logo in terms of details and gradients, the higher the risk that the actual print will not match the screen mockup. It makes sense to always request a color proof before launching a print run — this is cheaper than redoing a batch of packaging after printing.
