This roundup covers the questions most frequently asked about Midjourney: why the image dimensions are off, how to keep a consistent style, and how to reproduce the same look using a Seed. Each question includes step-by-step actions you can follow directly to avoid repeated trial and error.
1. Incorrect output size: How to choose aspect ratio, cropping, and upscaling
Midjourney’s sense of “size” is mainly determined by the aspect ratio. The most commonly used option is to add --ar 1:1, --ar 16:9, or --ar 9:16 at the end of the prompt. If you find the subject looks squeezed, it’s usually because the ratio doesn’t fit the subject matter—switch to a ratio closer to your intended composition and regenerate for more reliable results. Upscale only enhances details within the original composition; it won’t recompose the image. If you want to expand the canvas, use Zoom Out, or enable Remix and modify the prompt while expanding.
2. Inconsistent style: How to stabilize a single visual style
To keep a set of images consistent in Midjourney, first establish a “style anchor”: fix key terms (such as lens, lighting, and materials) and reduce random adjectives. Next, you can use an image you like as a reference and bind the style source with --sref, then change only the subject while keeping the style anchor unchanged. Style drift usually happens because prompts get messier and messier over time. It’s recommended to save your commonly used style paragraph as a template and only replace the subject nouns each time.
3. Seed reproduction: Why “the same sentence” generates differently
Midjourney is random by default, so even the same prompt can produce variations. To reproduce a similar composition, add --seed [number] at the end of the prompt and keep other parameters as consistent as possible (for example, the same --ar, the same model, and the same mode). If you’re iterating based on a particular image, start from that image’s Job information and then make small wording adjustments. Note: Seed is a “similar starting point,” not a pixel-perfect duplicate—the more you change the wording, the more it will drift.
4. Broken details (hands, text, structure): A more practical repair workflow
If you run into problems with fingers, facial features, or structure, don’t rush to reroll many times. First, pick the closest image and do a targeted redraw (Vary Region) in Midjourney—select only the problematic area and clearly specify the “correct structure” in the added prompt. For text content, try not to have the model generate long passages; switching to “blank space / no text labels / simple symbols” tends to look cleaner. For images that feel “too busy” or “too chaotic,” reducing stacked adjectives and increasing the priority of the subject description is often more effective than tweaking parameters alone.
5. Prompt blocked: How to tell whether it’s a wording issue or a content issue
When Midjourney blocks a prompt, it’s usually not because “the system is broken,” but because the prompt triggered a sensitive category or used overly explicit descriptions. Replacing risky words with more neutral phrasing often gets it through. It’s recommended to first remove details that are prone to false positives (body parts, violence descriptions, directly naming celebrities, etc.), then add sections back one by one to test which part causes the block. If similar themes fail frequently, generate a base image with more general descriptions first, then refine gradually—this is more reliable than stuffing everything into a single prompt.
