Choosing the right electronic shelf label starts with the hardware. Labels that fit your shelving, display clearly at browsing distance, and run for years without battery swaps are the foundation of a pricing system that works without adding to your team’s workload.
We carry a range of label sizes and formats. This page helps you figure out which ones make sense for your business.
Electronic Shelf Labels: Models and Form Factors
MarginMate deploys the Pricer SmartTAG Color line, a range of digital wireless price labels built on four-color e-paper display technology. Each model is designed for a specific shelf environment, with battery life measured in years, not months.
Choosing the Right Label Size for Your Store
Most retail environments use a mix of label sizes: compact labels on dense peg hook fixtures, standard sizes on gondola shelf rails, and larger formats in showroom or high-ticket sections. The table below maps common store environments to the label sizes that typically perform best.
| Store Environment | Recommended Size(s) | Notes |
|---|---|---|
| Grocery/supermarket (standard aisle) | 2.2" - 2.6" | High SKU density; standard shelf rail mounting; unit pricing fields visible at normal browsing distance |
| Grocery/supermarket (produce, deli, bulk) | 2.6" - 4.3" | More display area for weight-based pricing and compliance fields; wider gondola rails are common |
| Liquor & beverage retail | 2.2" - 2.9" | Frequent promotional changes; labels must handle rapid price cycling without display degradation |
| Convenience store / micromart | 1.6" - 2.2" | Compact fixtures; limited shelf rail space; high-density label placement common |
| Furniture showroom / large-format | 4.3" - 7.5" | High-ticket items; labels serve as product descriptor panels; readability from several feet matters |
| Freezer doors and specialty fixtures | 2.2" - 2.6" | Temperature-rated mounting accessories required; standard label sizes apply across most freezer door rail systems |
| Peg hook / slatwall (hardware, specialty) | 1.6" - 2.2" | Space-constrained mounting; compact labels with peg-compatible accessories |
The MarginMate team conducts a store layout assessment during deployment planning to confirm the right label mix for each section and fixture type.
How Wireless Price Tags Communicate and Update
- E-paper display technology holds its last image without consuming power. The label only draws energy when a price change requires a refresh, which is why battery life extends to 8-10 years under normal retail pricing cycles.
- Updates are delivered through MarginMate’s infrared (IR) communication infrastructure, not store Wi-Fi. Each label receives its update directly, without network contention or signal interference from other in-store devices. This is covered in full on the Electronic Shelf Labels page.
- The four-color e-paper display renders pricing, promotional fields, barcodes, and unit pricing information in a single refresh. No ongoing power draw for a static display.
- SmartFLASH LED (available on compatible models) activates on demand in under one second to guide staff to a specific shelf location. LED activation draws from the same long-life battery without meaningfully reducing its operational lifespan under normal use patterns.

Mounting, Fixtures, and Installation Compatibility
The most common pre-installation question is whether the labels will work on existing store fixtures. In most cases, yes – the SmartTAG Color range is designed to mount on the fixture types found across the majority of North American retail environments.
| Fixture Type | Compatibility Note |
|---|---|
| Standard gondola shelf rails | Compatible with the most common label clip and rail systems used in grocery, liquor, and specialty retail |
| Peg hooks and slatwall | Compact label sizes (1.6"-2.2") with peg-compatible mounting accessories |
| Freezer and refrigerated cases | Temperature-rated mounting solutions; standard label sizes apply |
| Display cases and specialty fixtures | Bracket and adhesive mounting options available for glass case and non-standard fixture applications |
| Furniture and large-format shelving | Larger label formats (4.3”+) with floor-standing and wide-rail mounting options |
Infrastructure installation is handled by your existing low-voltage contractors as part of the MarginMate deployment. This keeps installation labor outside MarginMate’s margin structure and gives you control over who does the in-store work.
