Valentine's Day 2026: 80 Copy-Paste Prompts for Gemini (Cards, Couple Photos, Instagram)

Lisa Ernst · 25.01.2026 · Artificial Intelligence · 9 min

For Valentine's Day productions, I often need 'quick good': a visual for the team, a card motif for the café, a reel cover that doesn't look like stock. These 80 prompts are built for that: copy, run, done. Valentine's Day 2026 is on Saturday, February 14 ( Source).

What Gemini really needs for image prompts

When you generate images in Gemini, depending on the interface and mode, you land very close to Imagen workflows. The official guide describes image generation, including important parameters like aspect ratio and person generation ( (Source).

Two details save the most time in practice: (1) Format (1:1 vs. 4:5 vs. 9:16) and (2) clear image attributes (Subject, Context, Style). Google describes these prompt building blocks (Subject, Context, Style) in the Prompt Guide ( (Source).

Format Check: which aspect ratio for what?

For social media, the common ratios are not 'nice to have,' but determine whether your motif looks cropped in the end. Ratios like 1:1, 3:4, 4:3, 9:16, and 16:9 are documented in Vertex AI/Imagen ( (Source).

Use Case	Ratio	Why it fits
Instagram Story / Reel Cover	9:16	Full-screen on the phone, less cropping.
Instagram Feed (Portrait)	4:5	Large in the feed, looks 'full' without a banner look.
Square Post / Sticker	1:1	Clean for icons, sticker sheets, card motifs.
Header / Website Banner	16:9	Suits hero-style layouts and thumbnails.

Negative Prompt: helpful – but not always available

Negative Prompts are documented in Vertex AI to specifically omit content ( (Source). It also states that it is a legacy feature and is no longer included in newer Imagen models (from imagen-3.0-generate-002) ( (Source). That’s why the 'Negative prompt' lines below are intended as an option: if your interface offers a field for it, use it – otherwise, strike the line.

People Safety: better to clearly write "Adults"

Person generation is described in the model parameters, including regional restrictions ( (Source). That’s why the Couple Prompts consciously include "two adult people" so you run into filters less unnecessarily.

Valentine's Day 2026 Prompts for Gemini: Cards & Typography

Cards work most reliably when you clearly state the material, print look, and layout. Google shows in the Prompt Guide that structured specifications (Subject, Context, Style) increase image control ( (Source). If text is crooked: generate motif without text and set text later in the layout tool – faster than ten new generations.
