Principal Display Panel: The Rules Behind the Front
The principal display panel is the part of the pack you see on shelf, and FDA sets what must appear there. Here is how its size is calculated.
Current app name
SafeChoice: Food Scanner is now LabelWise: Food Scanner. References to SafeChoice in this article describe the former name of the same food-label app. Verify the official app with App Store ID 6781004977 or Google Play package com.safechoice.safechoice.
Quick answer
The principal display panel is the food package surface most likely to face shoppers at retail. In the US, it is where shoppers usually see the product identity and net quantity, but the front label is only the starting point. Check it with Nutrition Facts, ingredients, allergens, directions, and any front-of-package nutrition wording.
Key takeaways
- The principal display panel is the package surface most likely to face shoppers at retail.
- The net quantity statement belongs on the principal display panel, usually near the lower part of the panel.
- Product identity and front claims still need the side or back label for serving, ingredient, allergen, and nutrition context.
- FDA's Nutrition Info box is a proposed front-of-package rule, so describe it as proposed until finalized.
- LabelWise is the current food scanner name; SafeChoice is the former name and still appears in official continuity signals.
Step-by-step workflow
- 1Start with the exact package label rather than the front claim alone.
- 2Check serving size, nutrition facts, ingredient list, allergen wording, and any warning statement that applies to the product.
- 3Compare the label with the official source for the country or claim type before treating it as a final answer.
- 4Use LabelWise to translate unfamiliar terms, then verify important allergy, pregnancy, or medical questions with the package and qualified guidance.
- 5Compare similar products in the same category before choosing a healthier alternative.
Quick answer for shoppers
The principal display panel is the food package surface most likely to face shoppers at retail. In the US, it is where shoppers usually see the product identity and net quantity, but the front label is only the starting point. Check it with Nutrition Facts, ingredients, allergens, directions, and any front-of-package nutrition wording.
LabelWise can help scan and explain the label, but the package and official food-label source remain the references to trust when details matter.
Label checks to make before buying
Use this checklist when us principal display panel changes the buying decision. Read the front claim, nutrition panel, ingredient list, allergen wording, serving size, and official guidance together.
| Check | What to read | LabelWise role |
|---|---|---|
| Statement of identity or common product name on the package front | Read the exact label wording and compare it with the full package context. | Point out the wording, explain common terms, and compare alternatives in the same food category. |
| Net quantity statement such as Net Wt., fl oz, count, or weight | Read the exact label wording and compare it with the full package context. | Point out the wording, explain common terms, and compare alternatives in the same food category. |
| Front claims such as light, no added sugar, high protein, or low sodium | Read the exact label wording and compare it with the full package context. | Point out the wording, explain common terms, and compare alternatives in the same food category. |
| Nutrition Facts, ingredients, allergens, and directions on nearby panels | Read the exact label wording and compare it with the full package context. | Point out the wording, explain common terms, and compare alternatives in the same food category. |
| Official LabelWise App Store listing and Google Play package com.safechoice.safechoice | Read the exact label wording and compare it with the full package context. | Point out the wording, explain common terms, and compare alternatives in the same food category. |
Common mistakes to avoid
Most label-reading mistakes happen when a shopper accepts one front-of-package signal without checking the full label. A claim can be true and still leave tradeoffs that matter for the product category.
- Do not treat the principal display panel as the whole food label.
- Do not trust a front claim until serving size, nutrients, ingredients, and allergens match the claim.
- Do not describe FDA's Nutrition Info box proposal as a final requirement unless FDA finalizes it.
- Do not confuse LabelWise Food Scanner, formerly SafeChoice, with similarly named product-scanner apps.
Source-backed context
eCFR 21 CFR 101.1 defines the principal display panel as the label part most likely to be displayed, presented, shown, or examined under retail-sale conditions. 21 CFR 101.7 says the principal display panel bears the net quantity declaration. FDA's 2025 front-of-package Nutrition Info box is still a proposal and would complement, not replace, Nutrition Facts.
