Nano Banana Pro features and prompt templates
If your goal is not just “a nice-looking image” but clear, accurate, reusable visuals (charts, SOPs, teaching diagrams, slides), your prompt should read like a spec. This post combines Nano Banana Pro strengths with a small library of templates you can reuse in real work.
1) When Nano Banana Pro is a good fit
- Structured outputs: modules, alignment, hierarchy
- Multi-round edits: iterate copy, numbers, colors while staying consistent
- Layout control: slides, posters, teaching materials
A common workflow is: nanobanana2 for fast exploration → Nano Banana Pro for final delivery.
2) A simple universal formula
Subject + details + style + parameters
- Subject: what you’re making (timeline / chart / flowchart / infographic)
- Details: data, labels, sections, rules
- Style: minimal / playful / corporate / hand-drawn / blueprint
- Parameters: aspect ratio, resolution, text readability constraints
3) Reusable prompt templates (8 types)
Replace placeholders in [ ].
1) Simple project plan
Create a clean project plan chart. Goal: [GOAL]. Timeline: Week1 [TASKS], Week2–3 [TASKS], Week4 [TASKS]. Layout: columns by week, clear labels, minimal business style, white background, blue/gray palette. Output 16:9, high-res.
2) Study concept map (hierarchy + arrows)
Turn these notes into a concept map with correct relationships and clear hierarchy: [NOTES]. Style: clean study-note infographic, white background, minimal accent colors, readable typography. Output 3:4, high-res.
3) Line chart (explicit data)
Generate a line chart. X-axis: [TIME]. Y-axis: [METRIC + UNIT]. Data points: [LIST]. Line style: [COLOR, WIDTH]. Points: [STYLE]. White background with light grid lines. Title: [TITLE] (bold). All text readable. Output high-res, no watermark.
4) Bar chart (colorful but readable)
Generate a bar chart. X-axis: [CATEGORIES]. Y-axis: [METRIC + UNIT]. Data: [LIST]. Bars: [GRADIENT COLORS], subtle gloss. Background: [WHITE or LIGHT TEXTURE]. Title: [TITLE]. Ensure all labels and numbers are readable. Output high-res.
5) Pie / donut chart (percentages + legend)
Create a donut chart with categories and shares: [LIST]. Distinct colors, labels with percentages (bold), legend aligned on the right. Light gray matte background. Title: [TITLE]. Output high-res.
6) Timeline roadmap (milestones)
Create a business roadmap timeline. Title: [TITLE]. Milestones with dates: [LIST]. Gradient main line, different colored nodes for phases, balanced symmetric layout, readable text. Output 16:9, high-res.
7) Flowchart (node shapes rule)
Create a clear flowchart: Start → [Step1] → [Step2] → … → End. Start/End are circles, steps are rounded rectangles, decisions are diamonds. Solid arrows with clear direction. White background, minimal style. Output high-res.
8) Ticket-style info card (coupon/entry pass)
Design a ticket-style info card. Theme: [THEME]. Brand: [BRAND]. Store: [STORE]. Offer: [OFFER]. Price range: [PRICE]. Strong but clean color contrast, clear hierarchy, all text readable, no watermark. Output 3:4, high-res.
4) Common failure points and fixes
- “Looks right but data is wrong” → list every value explicitly and require correctness.
- Garbled text → require “fully readable text, no distortion” and avoid tiny fonts.
- Crowded layout → cap each module to 3–5 lines and demand whitespace.
