Why Does My Full-Size Desk Look Like a Miniature When a HeyGen Avatar Holds It?

Match the Product to the Demonstration

A perfume bottle and a full-size office desk require different visual explanations. A person can naturally hold a perfume bottle while discussing its packaging. A desk is normally understood through its relationship to a room, chair, and standing or seated person.

HeyGen's Product Placement combines a product image with an avatar and is designed primarily for handheld presentation. The documented behavior warns that large objects may be reduced in apparent size.

Before selecting this workflow, identify the physical action the advertisement should communicate. Is the avatar presenting a small item, or must the audience understand how a large object occupies real space?

Decision branch: Evaluate handheld placement when holding the product is plausible. For furniture or other large objects, consider a composition that communicates environmental scale without implying the avatar can hold the full-size item.

Separate Relative Scale From Product Identity

A generated desk may retain recognizable colors and shape while appearing far smaller than the merchandise being sold. This creates a different problem from incorrect branding or missing product components.

The merchant should distinguish visual identification from physical-size communication. A miniature-looking desk might be acceptable in an explicitly stylized concept, but it should not silently replace a demonstration intended to communicate actual furniture proportions.

Prepare a brief describing the intended relationship between product and presenter. For small merchandise, hand-held presentation may support the message. For large merchandise, the brief should specify an environmental context or another approved representation.

Do not use apparent size in a generated avatar scene as measured dimensional evidence. Verify any factual dimensions against approved product specifications rather than estimating them from the image.

Illustrative Exercise: Perfume Versus Furniture

Illustrative exercise — fictional advertising requests, not executed HeyGen generations or account tests.

Input A is a perfume advertisement in which an avatar introduces a bottle and discusses its packaging. The intended action is a plausible handheld presentation.

Input B is an office-furniture advertisement requiring customers to understand a full-size desk's proportions. An avatar holding the desk would conflict with that communication goal.

Decision branch: Evaluate Product Placement for A, while reviewing whether the bottle appears suitable for the approved presentation. For B, choose a different creative arrangement before committing to the handheld concept.

Review the Image Stage Before Continuing

Before treating the proposed placement as an approved advertising visual, inspect the product's apparent size relative to the avatar. Ask whether the relationship communicates the intended product category accurately.

For handheld items, review the grip, product visibility, and whether important packaging features remain recognizable. For large objects, check whether the composition falsely suggests a miniature product.

If the physical relationship is unsuitable, revise the presentation brief instead of repeatedly requesting the same handheld arrangement. Preserve the approved product photograph and specifications for comparison.

The official documentation establishes a suitability limitation, not a promise that the system will reproduce real-world dimensions. This review process is editorial guidance and does not establish a tested generation outcome.
